However, different from the differential casting for medal, the mould used here is made from silicon rubber belonging to super-elasticity materials and the filling material is Polyamine resin whose viscosity varies within a larger range [3, 4].
Therefore, a silicone rubber-based finite element model is established, fully considerding silicone rubber materials nonlinearity, geometric nonlinearity and incompressible properties.

Similarly, Chen and Li [6] found from their finite element simulation that the maximum erosion loss happened at 30° impact angle for ductile materials, and 90° impact angle for brittle materials.

In materials of distinct ductile behaviour, fracture occurs after all three phases.
Materials: Basic mechanical properties of the materials (base metal - BM and weld metal - WM), determined on round tensile (RT) specimens, are given in Table 1, while the true stress - true strain diagrams of both materials can be found in [18].
Using this procedure, values for both materials from Table 1 are determined.

Introduction Carbon nanotube (CNT) is one of the attractive reinforcements of the composite materials due to its low density of 1.3 g/cm3 and 973 GPa Young's modulus [1,2].
Experimental Atomized pure Ti powders, having a mean particle size of 30 μm, was used as starting materials.
P/M extruded TMC materials were machined to tensile specimen bars with 3.0mm diameter and 10 mm gauge length, and evaluated at room temperature.
A mean grain size of P/M Ti materials with CNTs and no CNT is around 6μm and 5μm, respectively, and no significant difference between them is observed.

Introduction Concrete is one of the most important structural materials.
Damage Model and Damage Index The Li Jie damage model was established for ideal brittle materials, because the spring element can only described the elastic of concrete.
However, for quasi-brittle materials like concrete, the plastic deformation will present after the elastic stage.

Preliminary results show that the model succeeds in predicting the trends in relation to segregation and intergranular fracture strength behaviour in these materials.
The proposed hypothesis will help the design engineers to select and use the materials in structural/load bearing applications.
