Abstract
A system and method for calculating stress in a device includes receiving an analytic solution domain and calculating initial analytic values for displacement and stress for a dislocation in the domain and creating a stress profile using the initial displacement and the initial stress as initial values of a stress equilibration equation.
Claims26
A stress simulation system comprising:
- a memory;
- and
- a processor, wherein the processor is configured to execute instructions from the memory that, when executed by the processor, cause the processor to:
- calculate an initial analytic solution for an initial displacement (u0) and an initial stress (σ0) in an analytic solution domain;
- and
- simulate a stress profile for an extended domain using the initial displacement and the initial stress as initial values of a stress equilibration equation.
