|Video: Non Linear Analysis||
Nonlinear stress analysis with SolidWorks Simulation enables designers and engineers to quickly and efficiently analyze stresses and deformations under general conditions while they are creating their design to ensure high quality, performance, and safety.
Tightly integrated with SolidWorks CAD, nonlinear stress analysis using SolidWorks Simulation can be a regular part of your design process. You can use the Simulation results to validate your part or assembly while you are designing, reducing the need for costly prototypes, eliminating rework and delays, and saving time and development costs.
Nonlinear Stress Analysis Overview
Nonlinear stress analysis calculates the stresses and deformations of products under the most general loading and material conditions for:
- Dynamic (time dependent) loads
- Large component deformations
- Nonlinear materials, such as rubber or metals, beyond their yield point
Nonlinear analysis is a more complex approach, but results in a more accurate solution than linear analysis, if the basic assumptions of a linear analysis are violated. If the linear analysis assumptions are not violated, then the results of a linear and nonlinear analysis will be the same.
The time component when carrying out a nonlinear analysis is important, both in controlling the loading (individual load components can be active at different times) and in capturing the response to an impulse load of impact. SolidWorks Simulation provides either an automatic or a manual time control method with a force, displacement, or arc length convergence control. You get power and flexibility to solve challenging and complex simulation problems simply in a straightforward manner.
SolidWorks Simulation uses finite element analysis (FEA) methods to discretize design components into solid, shell, or beam elements and uses nonlinear stress analysis to determine the response of parts and assemblies due to the effect of:
- Contact between components
Loads can be imported from thermal and motion Simulation studies to perform multiphysics analysis.
In order to carry out stress analysis, component material data must be known. The standard SolidWorks CAD material database is pre-populated with materials that can be used by SolidWorks Simulation, and the database is easily customizable to include your particular material requirements.
