1.What is theories of failure?

Question

Accepted Answer

Theories of failure are mathematical models used to predict the failure of materials under different loading conditions.

Theories of failure help engineers design structures that can withstand different types of loads.
Some common theories of failure include maximum shear stress theory, maximum normal stress theory, and maximum strain energy theory.
These theories are based on different assumptions about the behavior of materials under stress.
For example, the maximum shear stress theory assumes that failure occurs when the maximum shear stress in a material exceeds a certain value.
The maximum normal stress theory assumes that failure occurs when the maximum normal stress in a material exceeds a certain value.
The maximum strain energy theory assumes that failure occurs when the total strain energy in a material exceeds a certain value.
Engineers use these theories to determine the safety factor of a structure and make sure it can withstand expected loads.
