Description
The standard bonded-particle models available in many discrete element method (DEM) codes are known to predict unrealistically low values for the ratio of ultimate compressive strength (UCS) to tensile strength (UTS) for concrete. To correct this,...

Description
Shot peening is a commonly used technique for improving the fatigue life of machine components by inducing compressive residual stresses in the surface layers. This process involves plastically deforming the surface layers by impacting the surface...

Description
In this work, a new machining model using the commercial finite element software ABAQUS is developed. The model regards material separation, chip serration and breakage as ductile fracture processes where energy is required to form new surfaces. T...
