Mechanical engineers leverage a wide variety of finite element analysis tools to make sure that products not only look good but also operate reliably and meet design specifications. The most common type of FEA is used to calculate how a product will respond to forces, such as tension, compression, and bending. This type of FEA is also referred to as Mechanics or Dynamics of Structures. For this type of FEA, the engineer will generate a finite element mesh of their model using either a mesh generator or by manually generating the mesh using a variety of elements, such as beam elements, face elements, tetrahedral elements, etc. Once the mesh is generated, the engineer will define the physical properties of the model, such as linear elastic material parameters, densities, forces and moments, and boundary conditions. Next, they will analyze the results using post-processing tools such as stress, displacement, and force diagrams.
With Mechanics/Dynamics of Structures FEA, engineers are able to simulate the product’s response to static, dynamic, and transient loading conditions. This type of FEA allows engineers to conduct virtual testing and evaluate the behavior of their model under a wide range of conditions. They can determine the maximum and minimum stresses, deformations, and other parameters in their model. Consequently, engineers are able to identify potential failure and design issues before manufacturing begins.
The main benefit of using FEA is that it eliminates the need for building and testing physical tools, prototypes, and models. It is also cost effective since engineers can test multiple design iterations using a single FEA model and compare the cost of the different designs. This allows them to determine the best design before the project is put into production. Additionally, FEA with Dynamics/Structures is a great way for engineers to evaluate the effect of their designs on the environment. For example, engineers can use FEA tools to see how their product will behave as waves sweep across the ocean surface. This method of testing is safer and more cost-effective than field testing and helps ensure product performance in a variety of environments.
Using FEA to solve Mechanics/Dynamics of Structures is an effective engineering tool that can help engineers design more reliable and efficient products. The finite element meshes allow engineers to model non-linear physical systems in order to determine the most effective design. In addition, FEA with Dynamics of Structures can help engineers find potential failure modes in their designs before any physical testing is preformed. Finally, the cost-effectiveness of FEA allows them to rapidly test a variety of designs and to make informed decisions about their products.
