Understand How Stress Analysis Works

Stress analysis is done using a mathematical representation of a physical system composed of:

• A part or assembly (model).
• Material properties.
• Applicable boundary conditions (loads, supports), contact conditions, and mesh, referred to as preprocessing.
• The solution of that mathematical representation (solving).

  To find a result, the part is divided into smaller elements. The solver adds up the individual behaviors of each element. It predicts the behavior of the entire physical system by resolving a set of simultaneous algebraic equations.

• The study of the results of that solution is referred to as post-processing.
