Critical Shear Stress in Materials Science Formulas

Critical shear stress is either the fiber-matrix bond strength or the shear yield stress of matrix, whichever is lower. And is denoted by τ_c. Critical Shear Stress is usually measured using the Megapascal for Pressure. Note that the value of Critical Shear Stress is always positive.

FAQ

What is the Critical Shear Stress?

Critical shear stress is either the fiber-matrix bond strength or the shear yield stress of matrix, whichever is lower. Critical Shear Stress is usually measured using the Megapascal for Pressure. Note that the value of Critical Shear Stress is always positive.

Can the Critical Shear Stress be negative?

No, the Critical Shear Stress, measured in Pressure cannot be negative.

What unit is used to measure Critical Shear Stress?

Critical Shear Stress is usually measured using the Megapascal[MPa] for Pressure. Pascal[MPa], Kilopascal[MPa], Bar[MPa] are the few other units in which Critical Shear Stress can be measured.
