The Rise of Heavy Industry 1980

Wang Chaoyang couldn't help but secretly praise Zhang Miaomiao's reaction speed, which was thorough at one point.

From a theoretical point of view, the mathematical model of the steel plate and the wooden door is basically the same, ignoring the Z-direction displacement, and the stress and displacement in the X and Y directions are the key points to consider.

Although the mechanical characteristics of bulletproof steel plates and wooden doors of armored vehicles are very different, the trend is the same.

Because of his experience in computer-aided simulation, Wang Chaoyang easily formed a grid model in his mind. It feels like removing all the material of the wooden door and replacing it with a spider web of warp and weft, and with the help of the computer, different stress areas will be displayed in different colors (usually red is the most dangerous, yellow is second, and green means no danger).

This sense of intuition is the power of computer aid.

But Zhang Miaomiao obviously does not have this intuitive feeling, she needs to analyze it from the perspective of mathematical models.

Time passed little by little, and Wang Chaoyang stared at the wooden door in a daze. Zhang Miaomiao has been squatting on the ground to write and draw, if this scene falls in the eyes of outsiders, I am afraid it will be incredible.

The two people in the predicament did not panic or shout, one was in a daze, and the other was at ease to analyze the finite element ......

"I've found the answer!" At

one moment, Zhang Miaomiao suddenly raised her head, her face full of excitement.

"Tell me about it. Wang Chaoyang said.

"The weakness is in the segment difference of material properties, and the stress concentration is the most serious!" Zhang Miaomiao said.

"Where's the break?" Wang Chaoyang said.

"Between the door panel of the wooden door and the longitudinal beam!" Zhang Miaomiao said.

"We have hope to get out of trouble!" Wang Chaoyang said with a smile.

The conversation between the two is simple, but the amount of information contained is huge. According to the structural strength theory, the discontinuity of the material properties is the weak point of the structural strength, which is reflected in the finite element analysis, which is the singularity of the stress curve. Zhang Miaomiao knew the singularity through finite element calculation experience, while Wang Chaoyang knew it based on the graphical judgment of computer-aided calculation.

If someone else is listening, they don't know what the two are talking about. But it was just a few simple conversations, and the two had already communicated.

Next, I saw Zhang Miaomiao get up again, pick up the stone again, and walk towards the wooden door leisurely.

This dilapidated kiln has been abandoned for more than ten years, before it was abandoned was a quarry barracks, the wooden door was made of old pine wood in the mountains, and the carpenters at that time used more than 20 centimeters thick pine planks to save trouble...... If placed in the future generations, the wooden door of this solid wood alone will be worth a lot.

After more than ten years of wind and sun, the wooden door has decayed in many places, but it is still very strong. So Zhang Miaomiao tried her best before, but she couldn't shake it at all.

This time, the girl did it again, and the only difference was the tapping position. The door panel close to the longitudinal beam made an "empty" sound under the knock of the stones, and soon a crack appeared in one of the door panels. After a few more knocks, the crack widened, and eventually a large hole appeared.

The hole was still not enough for the two of them to get out, but Zhang Miaomiao could stretch out her arm to reach the latch. The latch is not locked, it is just plugged in, and Zhang Miaomiao can pull the latch open.

The wooden door creaked open, and a gust of air rushed into the room, causing the two people in the room to be in high spirits at the same time.

"Success!" Zhang Miaomiao said happily.

"We really shouldn't die!" Wang Chaoyang said with a smile.

"I never thought that finite elements would be of such use!" Zhang Miaomiao said.

"I won't forget this finite element experience for the rest of my life, right?" Wang Chaoyang said.

"Well, I will never forget it for the rest of my life!" Zhang Miaomiao said.

With Zhang Miaomiao's support, Wang Chaoyang walked out of the door. Looking far away, it is a boundless barren mountain and dry grass, no wonder the wind is cold and hard, this is actually a barren mountain and wild range.

There was no moon at night, the sky was clear, and by the starlight, the two of them could see the outline of the mountains and fields in the distance, full of slaughter, like countless giant beasts crawling on the ground.

"Where do you go next?" Zhang Miaomiao asked.

"Just go ahead...... Anyway, I don't know where this is, to see if I can find someone. Wang Chaoyang said.

"Hmm!" Zhang Miaomiao said.

The two of them supported each other and walked into the distance, and at the same time, behind a large stone nearly thirty or forty meters away from the broken tile cold kiln, Xie Feijun was sleeping in a leather jacket.

Xie Feijun didn't know Wang Chaoyang and Zhang Miaomiao before, and it was a pure coincidence that he undertook the task of giving people away this time.

However, just before he set off, he was called by Captain Xu of the transport team and ordered to kill two people from the Red Star Factory. Xie Feijun is not an outlaw, but he is a good gambler, and several times Xu San helped him get out of trouble, and he didn't dare to disobey what Xu San told him.

His plan was to drive the car out into the wilderness, then make a rollover, and then lock the two of them in a pre-planned dilapidated kiln, he planned to leave until midnight, drinking while guarding, but fell asleep in the first half of the night.

I slept until midnight, and when I got up to pee, I took a look at the house.

It doesn't matter if you don't look at it, this look suddenly has no intention of urinating, and the wooden door of the house has been opened!

Xie Feijun lifted his pants, ran to the house in a panic, and went inside to take a look, where else were the shadows of Wang Chaoyang and Zhang Miaomiao.

"It's too bad, it's too bad, I lost people, and the third brother knew that I had to kill me!" Xie

Feijun had always known Xu San's style, so he didn't have time to hesitate, so he started chasing. He didn't know the direction of Wang Chaoyang and Zhang Miaomiao, but now his mind was full of Xu San's angry expression, he couldn't care too much about it, and chased aimlessly.

Stumbling and running, I don't know how long I did, a light appeared in my field of vision.

Xie Feijun suddenly slowed down. After looking closely, I saw that the light in the distance was a bonfire, and there were three figures around it.

Xie Feijun slowly approached, and finally recognized the people next to the bonfire, it was Wang Chaoyang and Zhang Miaomiao, and there was another young man next to the two.

Xie Feijun knew that Wang Chaoyang's injuries were very serious, and he didn't pay attention to Zhang Miaomiao and the young man, so he rushed over without thinking about it.

Hearing someone rushing over, the three people around the fire were startled at the same time. Wang Chaoyang recognized that the person was Xie Feijun, and sighed in his heart, although there were three people on his side on the scene, he couldn't move, Zhang Miaomiao was a girl, and the other helper was still a half-old child, so he might not be useful.

The reality was as Wang Chaoyang expected, several people on his side couldn't control Xie Feijun at all, Zhang Miaomiao and the young man were pushed to the ground, Xie Feijun walked straight towards Wang Chaoyang, and muttered "I don't care about others, but you have to stay."

Wang Chaoyang secretly complained, it seems that he is the focus of "taking care of"!

If Wang Chaoyang was not injured, he might be able to compare himself with the other party, but now his legs hurt as soon as he exerts his strength, and now he can only be caught with his hands tied.

At the critical moment, Wang Chaoyang's composure that did not match his age played a role. When Xie Feijun rushed over, Wang Chaoyang grabbed a handful of sand with his backhand and raised it towards the other party's eyes.

Although this trick of "three indiscriminate" was shameful, it was very effective, Xie Feijun covered his eyes and shouted.
