0.5 x strain x volume 0.5 x stress x volume 0.5 x stress x strain 0.5 x stress x strain x volume
1/4 time 1/8 time 4 times 8 times
maximum principal stress theory maximum principal strain theory maximum shear stress theory shear strain energy theory
pure shear uniaxial stress only equal and opposite axial stresses on two mutually perpendicular planes, the planes being free of shear equal axial stresses on two mutually perpendicular planes, the planes being free of shear
Creep is deformation due to high temperature under no stress condition Creep is time dependent deformation under stress Creep is independent of temperature For a given level of stress, the rate of creep is independent of time
