Finite Element Analysis

DH Glabe & Associates performs finite element analysis (FEA or FEM) of structural components for buildings, bridges, tools, mechanical & electrical equipment, and other components that necessitate detailed structural analysis. Our FEA engineers provide linear and non-linear FEA depending on the specific requirements of the client. The goal of a finite element analysis is to determine the expected behavior or response of a physical object under imposed loads. The results of the analysis provide our engineers with information that will help them to understand how the object under consideration will bend, break, or perform safely under the imposed loads. 

A computational model of the physical object under consideration is developed using sophisticated structural analysis software by an experienced DH Glabe & Associates structural engineer. The material properties of the object are carefully determined and input into the model. The object is divided into a series of small elements called a mesh that together make up the whole of the object.

FEA Engineer Consultants

DHG engineers utilize RISA 3D for basic finite element analysis of less complex objects, Solidworks for more complex objects that require non-linear analysis, and LUSAS for bridges and larger complex structures. Once the object is accurately modeled in the computer software, loads are determined and input by the engineer based on the loading criteria established by the customer in conjunction with applicable codes and standards. We help our customers to interpret code requirements and regulations that often govern the loading criteria that is required for the analysis.

Often, specific loading criteria is required depending on the industry and application of the item being investigated. Some examples of some of the most common load types that DH Glabe & Associates considers when performing a finite element analysis include gravity loads, hydrostatic pressure, wind pressure, seismic forces, vibration, and thermal effects.

The results of the finite element analysis can be displayed graphically. The stresses in each element are determined and a contour is developed that illustrates for the DHG engineers and our customers how the stress changes throughout the object. Changing colors represent different degrees of stress. Our engineers are able to simply interpret and communicate to our customers the results of the analysis. A finite element analysis adds increased confidence in the structural integrity and strength of the object to safely perform in the manner in which it was intended. Contact us today to learn how our FEA engineers can help you with your next project.
