如何计算Youngs Modulus
learn.whatIsHeading
Young's modulus (E) measures resistance to axial deformation: E = stress / strain; defines material stiffness.
公式
Calculate E = σ/ε
- E
- σ/ε — σ/ε
分步指南
- 1Input axial stress and resulting strain
- 2Calculate E = σ/ε
- 3Results show material stiffness, usually in GPa
例题解析
输入
Steel: E ≈ 200 GPa
结果
Aluminum: E ≈ 70 GPa
Steel ~3× stiffer
常见错误注意事项
- ✕Confusing with strength (high E ≠ strong)
- ✕Not using consistent units
常见问题
Does Young's modulus depend on material processing?
Slightly; annealing can reduce E, cold-working can increase it, but primarily material-dependent.
