Looking at the mathematical model in front of him, Cheng Hao began to follow the method pattern to find the optimal solution to the mathematical model in front of him.
This process is not difficult to say the least. Considering Cheng Hao's mathematical skills, this process is not even as difficult as sorting out the data and mathematical models last night.
But after all, there is too much data. If Cheng Hao wants to obtain something, he must observe the entire mathematical model in front of him.
The pen in Cheng Hao's hand kept moving.
Calculate the optimal solution for the model in front of you.
In the end, at 11 o'clock in the evening, Cheng Hao still had not calculated the optimal solution.
“What exactly went wrong??”
Cheng Hao frowned and looked at the draft paper in front of him. It was densely written with formulas, but the optimal solution obtained above conflicted with the mathematical model he created!
Scratching his hair, Cheng Hao felt slightly crazy. He was very confident that he had mathematical calculation skills, but the current mathematical model was somewhat contrary to this aspect.
Is it really so difficult to calculate the direction of materials?
To be honest, in the field of computational materials science, I prefer chemistry majors, but chemistry and physics sometimes overlap, especially in materials.
After calming down for a while, Cheng Hao continued to look at the mathematical model in front of him.
At this moment, the little u next to the computer screen suddenly sent a message.
"Master, what is this bump on this mathematical model?"
Seeing Xiao u's words, Cheng Hao smiled.
He typed a string of characters at random.
"This was during the experiment. Some impurities were mixed in due to improper operation, which caused the mathematical model to be unable to be smoothed."
"Will these impurities affect the final numerical value of the material?"
Xiao u, the artificial intelligence, has been trained by Cheng Hao for a long time, and his learning ability has begun to improve.
"Generally not, unless there is large-scale impurity inclusion, such a small amount of impurity inclusion will not affect the final material value."
Cheng Hao said casually to Xiao u.
After saying that, Cheng Hao suddenly felt as if he was struck by lightning, and his eyes suddenly lit up.
That’s right! Large-scale impurity doping.
For the current mathematical model problem, why not try impurity doping?
Thinking of this, Cheng Hao went ahead and started simulating the mathematical model on b. Based on the previous data, Cheng Hao directly conducted a large number of simulations.
A large number of other materials were selected for simulation in the model.
Then do the numerical calculations!
Soon, Cheng Hao found the optimal solution!
A polyvinyl alcohol (PVA) composite material with a graphene content of 1.9vol% was coated on a titanium alloy material. Its mechanical properties were displayed according to the data on the mathematical model. It was found that the tensile strength of the composite material was compared with that of the simple titanium alloy material.
Increased by 150%, Young's modulus increased by about 5 times!
What's more important is that other aspects have been improved to varying degrees!
The polyvinyl alcohol (PVA) composite material with a graphene content of 1.9vol% is more like a paint!
The titanium alloy material itself has a strong foundation, and after adding this coating, it becomes even stronger!
"yes!"
Cheng Hao's eyes showed excitement, he finally found it!
After heaving a sigh of relief, Cheng Hao felt his head was dizzy and fell asleep directly on the bed.
The next day, the first thing Cheng Hao did when he woke up was to come to the laboratory with a USB flash drive.
"Professor! I've done it!"
Cheng Hao said excitedly to Academician Lin.
Academician Lin was stunned for a moment, and Zhou Ming and Zheng Sen looked at each other immediately, with a trace of hesitation in their eyes.
"Data, have you finished processing it?"
Academician Lin hesitated for a moment and asked Cheng Hao in front of him.
"right!"
With that said, Cheng Hao directly inserted the USB disk into the computer nearby.
The people nearby quickly gathered around, opened b, and scrolled, a huge mathematical model appeared in front of everyone.
"Damn it! My little brother's mathematical model is really beautiful!"
Zhou Ming looked at the mathematical model in front of him with some surprise.
Zheng Sen and Zhang Ming on the side also had shocked looks in their eyes.
At this time, Cheng Hao continued to click on the model to display the calculation results.
Academician Lin looked at the mathematical model in front of him seriously. He could tell that the mathematical model in front of him was not only beautiful!
What I did was really good. Soon, the data kept stacking and changing, and finally an optimal solution appeared.
"Polyvinyl alcohol (PVA) composite material with graphene content of 1.9vol% coated on titanium alloy material?"
Looking at the optimal solution in front of him, Zhou Ming had a look of doubt in his eyes. He looked at Cheng Hao in front of him and said, "Is there something wrong with your mathematical model?"
"Yes! Junior brother, we have also done similar experiments, using graphene and other materials to coat titanium alloys. If I remember correctly, we have also done it with polyvinyl alcohol, but the amount may not be right. I remember at the time
When doing it, there is no advantage at all in this kind of coating!"
Zhang Ming frowned, adjusted his glasses, and spoke with a slight hesitation towards Cheng Hao in front of him.
"First of all, in your experiment, there must be some "impurities" missing, and then the ionization process is missing!"
Cheng Hao smiled slightly and said to the three people in front of him.
"Impurities?"
"Yes! I mixed a little bit of PVC material into these PVA materials and the mathematical model!"
Cheng Hao smiled slightly and said with a smile towards the three people in the laboratory.
At this time, Zheng Sen on the side wanted to say something.
"Zhou Ming, go and reset the experiment and try it!"
Academician Lin on the side has already spoken.
"Oh! OK!"
Soon, everyone began to reset the experiment according to the data on the computer.
Follow the experimental procedures for computer data.
The graphene is separated, doped into the PVA solution, and then slightly doped with some PVC materials. After full dissolution, the titanium alloy is added, and finally ionized.
Finally, the titanium alloy was taken out.
The titanium alloy in front of them has changed a little, and a faint blue light appeared on it. Everyone around looked at the titanium alloy in front of them curiously.
Then conduct experiments on the mechanical level.
Experimental results: Compared with pure titanium alloy materials, the tensile strength is increased by 130%, and the Young's modulus is increased by about 3 times.
Looking at the experimental results in front of them, the eyes of the three people around Zheng Sen showed disbelief.
It's just an improvement on the layer. Why can the material itself change so much???
Strength increased by 130%!
You know, this is titanium alloy! And this is just the first experiment, and it can be optimized by changing the process in the future!
