Macro-Analysis
Description
Macro-analysis in the «Manipula» software package refers to methods for modeling the behavior of materials and structures at the macroscopic level. Built‑in solvers operate with global characteristics: stress, strain, and displacement. This method is used to solve problems in solid mechanics under static, dynamic, and thermal loads.
Manipula/SMCM 4.0 implements a modular approach to calculating composite structures—both 3D solid and 2D shell types. The following types of problems are supported:
- quasi‑static mechanics;
- heat conduction;
- thermoelasticity (coupled problems);
- modal analysis;
- forced harmonic vibrations;
- stability and thermal stability.
All macro-analysis modules account for the complex anisotropy of materials when calculating composite structures.
