For the purposes of analysis, granular materials are frequently idealized by stating that slip will occur when the stresses satisfy a relation depending on the angle of internal friction and cohesion. States of stress violating this rule are not permitted. From a simple mechanical model it is concluded that in dynamic problems the possibility of disintegration of the body must be considered, and that disintegration, if it occurs, is a boundary-layer phenomenon.
