I am trying to model the residual stress in the body, which is subjected high temperature gradients. In the process of cooling/solidification the residual stresses are formed in the member. I red many literature, they plotting the equivalent Von Mises stresses, to show the residual stresses in that body.
Equivalent Von Mises stress is often used to analyze and represent residual stresses in a body subjected to thermal gradients and other loading conditions for several reasons:
In the context of modeling residual stresses in a body subjected to high-temperature gradients during cooling and solidification, the equivalent Von Mises stress provides a comprehensive representation of the stress state, making it a valuable tool for predicting potential issues such as cracking, warping, or other forms of failure. Researchers and engineers often use finite element analysis (FEA) and other numerical methods to calculate and visualize these stresses, helping to guide the design and manufacturing processes to mitigate undesirable effects.
Thanks for the detailed explanation sir, I have small doubt, for a particular time instance, If Equivalent Von Mises stress is zero in the entire body. Can we consider that, the body has zero/no residual stresses. @Kristaq Hazizi
