Finite element analysis (FEA) solvers such as Abaqus are powerful tools for predicting the behavior of structures under load, but it’s important to remember that the assumptions of linearity underlying FEA can break down under certain conditions. When that happens, the results of the analysis may not accurately represent the real-world behavior of the structure.

Technological advancements in this space have allowed for increased speed, quality, and quantity in the manufacturing of this equipment. However, many mid-market manufacturers may find the adoption of new technology
It is likely that most simulation engineers have at least heard of the terms true-stress and true-strain before. But what do these terms mean, how do we calculate them and why are they important? This post aims to address all three of these questions. Engineering-Stress and Strain Before we delve into true-stress and strain, it
Tier 1, 2, and 3 suppliers are an integral part of the automotive manufacturing ecosystem, as evidenced by the fact that upwards of 75% of a vehicle’s parts come from these suppliers in a market worth nearly 3 trillion US dollars. In recent years, auto suppliers have experienced significant challenges. The automotive industry was already
All engineering materials like metals, plastics, glass, and concrete have limited lifetime. Various factors like fatigue, corrosion, erosion, stress corrosion cracking or foreign object damage effect the strength, stability, and chemical composition of the material leading to its failure. This post is aimed at summarizing some of the more common failure theories and providing guidance

The famous fourth dimension, ‘time’, plays a crucial role in determining the behavior of almost all engineering and physical systems. Given this, it is important that our FEA simulation methodologies account for time accordingly. This post is aimed at explaining the concept of time integration in FEA and the difference in how it is accounted
