I need to calculate a particular state of stress through a mathematical function in Abaqus and want to see the element's distorted status respectively. So I wonder, which subroutine will work to solve an embedded mathematical expression based on residual stress or distortion?
#Abaqus, #FEM Simulation, #Residual stress, #ANSYS

Hi Muhammad Qasim Zafar,
You can use predefined field of temperature type created as analytical field (type – expression field). Abaqus offers wide range of elementary functions over spatial variables. This way it is possible to obtain non-homogeneous thermal expansions (provided that expansion coefficient is nonzero) which can be treated as initial deformations for the next step.
Victor J. Аdlucky in the next step if I apply damage criteria based on the resultant residual stress calculated from a mathematical function then which user subroutine would be appropriate?
Muhammad Qasim Zafar Look at the proposed damage criteria in material properties. Maybe you will find the proper one and get by without subroutine.
