The static stress state at a certain point in a material is defined by three principals. The material is characterised by its tensile and compressive strengths ( equal for ductiles ).
This script computes the safety factor at the point using either :
- the maximum shear stress criterion (9) for ductiles, or
- the modified Mohr criterion (10) for brittle materials.
All stresses and strengths in the same units. Empty boxes default to zero.
