True or False
The critical resolved shear stress is not a property of the material?
Does the resolved shear stress depend on the tensile stress applied?
Homework Answers
False
Explanation-The critical resolved shear stress is a property of material .slip occurs when we consider resolved shear stress .slip occurs by dislocation of motion.by which stress also produces ,shear stress acting in the slip direction on slip plane .which is able to deform the material .that's why CRSS is a material property.
Yes
Explanation-the resolve shear stress is depends upon tensile stress .CSRR is material property so it depends upon tensile and compressive strength .it also depends upon type of orientation and temperature.
