Unit 13 Material failure

The material failure theory (or strength criteria) represents a way to predict the conditions under which solid materials fail under the action of external loads The aim is… . . . to find a index of the stress of the material, or equivalent stress σeq = σeq(σ1, σ2), to compare with the strength limit values measured in a uniaxial laboratory test (fr(T) in tension and fr(C) in compression)
