Welded steel structures are widely used in engineering applications such as bridges, offshore platforms, pressure vessels, and structural frames, where they are frequently subjected to repeated or cyclic loading rather than monotonic loads. Under such conditions, welded joints often become critical locations for damage initiation due to stress concentration, metallurgical ...

Fatigue and Cyclic Loading in Abaqus Mechanical fatigue is a phenomenon where a material undergoes progressive and localized structural damage when subjected to cyclic or fluctuating stresses, even if these stresses are below the material’s ultimate tensile strength. Over time, this repeated loading and unloading can lead to the initiation ...

In this tutorial, the Simulation of low cyclic fatigue damage based on hysteresis energy on Abaqus has been investigated. The steel plated is modeled as a two-dimensional part. You can see a figure of the assembled part below. It is well known that after a number of repetitive loading cycles, ...
