Stress Analysis tab

The Stress Analysis tab is used to specify the type of stress analysis, the parameters to include in the calculation and the matrix solver to use.

The Stress Analysis tab is only accessible for thermoplastic injection molding processes using a Midplane mesh type.

Small deflection
Small deflection analysis is the most common type of analysis and is the basis of both large deflection and buckling analysis. A thorough understanding of small deflection analysis is an important prerequisite for understanding the other analysis types.
Large deflection
The large deflection analysis provides the final deformed shape of the part, allowing for nonlinear stress-strain behavior within the part. In practice, most structures will exhibit a linear or approximately linear response only over a restricted range of load intensities. At higher loads the stiffness of the structure can alter significantly, leading to a non-linear response.
Buckling
A buckling analysis is used to determine whether the deformation of the part will be stable or unstable under the applied load(s). Whilst the full non-linear incremental/iterative method of following the response of a structure is completely general and relatively precise, it can also involve a great deal of computational effort.
Modal frequency
Select this analysis type if you want to determine the natural, undamped frequency response of the part. Theoretically, this analysis type is similar to the buckling analysis, however the physical interpretation of the results is different.
Creep
The creep behavior of the part is its time dependent deformation under the applied load(s).
