1. Friction modelling in numerical simulation of iron powder die pressing
Sammanfattning : .... LÄS MER
2. Modelling and simulation of powder pressing with consideration of friction
Sammanfattning : Finite element modelling and simulation of the powder pressing process can be used in the rational development of powder metallurgy (PM) components. Many of the nonlinear finite element (FE) codes available today can be used for powder pressing simulations. LÄS MER
3. Towards Discrete Element Modelling of Rock Drilling
Sammanfattning : The method of percussive rotary drilling is recognized as the most efficient method for hard rock drilling. Despite the clear advantages over conventional rotary meth-ods, there are still uncertainties associated with percussive rotary drilling. LÄS MER
