According to St. Venant's theory for brittle material, the shape of the yield locus is _

Arhombus

Bsquare

Cellipse

Dhexagon

Answer:

A. rhombus

Read Explanation:

St. Venant's theory states that the shape of the yield locus is a rhombus. This theory overestimates the behavior of ductile materials and fits well only with experimental results of brittle materials' biaxial tension. The Von-Mises criterion provides the best agreement between experiment and theory and is widely used.
