Maximum normal strain theory

Maximum normal strain theory

Finite strain theory Wikipedia

In continuum mechanics the finite strain theory—also called large strain theory or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions inherent in infinitesimal strain this case the undeformed and deformed configurations of the continuum are significantly different requiring a clear distinction between

Failure Criteria for Brittle Materials eFunda

The maximum stress criterion also known as the normal stress Coulomb or Rankine criterion is often used to predict the failure of brittle materials The maximum stress criterion states that failure occurs when the maximum normal principal stress reaches either the uniaxial tension strength s t or the uniaxial compression strength s c
