以下一个简单的 Python 实现杨氏模量的小程序:
```python
import numpy as np
def find_slope(x, y):
# 计算斜率
n = len(x)
slope = np.zeros(n-1)
for i in range(n-1):
slope[i] = (y[i+1]-y[i]) / (x[i+1]-x[i])
return slope
def young_modulus(slope, area, length):
# 计算杨氏模量
force = slope * area
stress = force / area
strain = stress / (length / 1000)
modulus = slope.mean() / strain.mean()
return modulus
x = np.array([1, 2, 3, 4]) # 输入应变数据点
y = np.array([10, 20, 30, 40]) # 输入应力数据点
area = 1 # 截面积
length = 10 # 样品长度
slope = find_slope(x, y)
modulus = young_modulus(slope, area, length)
print("杨氏模量为:", modulus)
```
此程序假设输入的应变和应力数据是已知的,并且它们按相同的间距排列。在实际情况下,可能需要根据实验结果来调整代码以适合特定的数据集。
