Which deformation results from exceeding shear stress in amorphous solids?

A)Formation of shear bands occurs
B)Elastic strain limit increases instead
C)Brittle fracture strength improves
D)Ductile necking becomes less likely

💡 Explanation

Shear bands form locally, because excessive shear stress causes localized plastic deformation via a mechanism called shear localization. Therefore, shear bands form rather than more uniform plastic flow, because amorphous solids lack a crystal lattice to facilitate dislocation movement.
