Timber is an orthotropic and naturally heterogeneous material whose mechanical behavior under bending loads is strongly influenced by grain orientation, material variability, and the presence of inherent flaws such as micro-cracks and knots. When subjected to flexural loading, these imperfections may act as stress concentrators, leading to crack initiation and ...

In this tutorial, Simulation crack growth in the RC beam under five points bending in Abaqus has been investigated. The concrete beam is modeled as a three-dimensional solid part. The bars and strips are modeled as three-dimensional wire parts. The rigid bodies as supporters and hydraulic jacks are modeled as ...

In this tutorial Simulation three dimensional fatigue phenomenon in Abaqus by using Paris law has investigated. Metal fatigue is the process by which a material is slowly damaged by stresses and strains that are less than those needed to actually break the material apart. For example, a steel wire might be ...
