Hill48 計算式
WebAug 17, 2016 · Stress/strain must be expressed in material coordinate system ( assumption of Hill48) To define strength in material axes, uniaxial tests are performed at 0/90/45 degrees. This is quite obvious. What we struggle to understand is whether the anisotropic axes are unique and the stress state must be expressed in this unique coordinate system.
