This is the grand-daddy of the ASME programs. It will prompt you for your output set and then calculate the ASME Stress Intensity, the ASME membrane stress (4-131) and ASME triaxial stress (4-137) for all plate elements in your model. A very powerful and useful utility for ASME pressure vessel analysis. If you are working with Appendix 4 Design Based on Stress Analysis, you will want to have this API in your tool chest.

This API program will contour the percent change in von Mises stress between two output sets.  One unique feature of the API is the ability to contour double sided planar.  This API has been set up to be a starting point that can be edited to contour the percent change of any output type.

Random Vibration Analysis

UPDATED!

The API will take PSD RMS displacement and stress components (the X, Y, XY components) from plates and solids (X, Y, Z, etc.) and calculate a conservative PSD RMS total translation and von Mises stress components.

After the API finishes, you can contour top and bottom plate stresses and also view the total translation. It is super useful!

One way of determining if a mesh is fine enough, is to look at how much the stress values differ between the centroid and the corner nodes; a large difference can mean that a mesh is not fine enough. This API calculates these differences for relatively high stress regions, and enters the results into the output set for viewing.

This API will calculate the axial and shear stresses for beam elements based on the element’s cross-sectional area. It will also calculate a simple combined stress measure (a pseudo von-Mises) based on the maximum bending stress + axial stress + shear stress). It is conservative and allows one to have a quick and simple way to determine if their beam elements are within their design guidelines.
