Matlab script:

Includes functions for calculating:

  • Principal stresses or strain in either 2D or 3D
  • Mohr’s circle and von Mises stress
  • Stress on an arbitrary plane defined by a unit normal vector
  • Thin-walled cylinder torsion with option for internal pressure
  • Deviatoric Stress Tensor
  • Octahedral Stress
