An Introduction to Stress Analysis with 3D CAD

Over engineering is costly to any design, so is guesswork but that shouldn’t be considered standard practice anyway. With the help of 3D CAD software, both can be avoided or replaced by reliable analysis that are easy to do.

Any modern 3D CAD software can perform advanced stress analysis for any part or assembly, if so required. The resulting data can later be exported to popular document formats for reporting and presentation purposes. The creation of the simulation is not hard to begin with, and the test results are dependable because all computations are done automatically thereby inhibiting human error. If a how-to resource is needed, Instructables has a vast library of user-created manuals for specific 3D softwares.

Before setting up the environment of the analysis, the user needs to define the material of the part. This is easily achieved by the simple selection of the material from updated libraries that are often packaged with the chosen 3D CAD software. If not available, then data can be user-inputted. For testing purposes, properties such as mass, volume, and density should be defined.

The next steps are intuitive. Setting up the environment is as simple as assigning a fixed area, and area that a set amount of forces, with the direction is applied. A simulation can then be run, wherein the result of the pull or the push is presented accompanied by a heatmap of the applied forces.

Design failure or over engineering can thus be easily predicted in controlled environments. This important design process has been simplified by 3D CAD, and as such, is no longer tedious to accomplish. This makes it more than ever easier to create machinery for any industry in the world that seeks efficient design.
