Vesic and Clough [7] consider that: This is because there is a broken value for the coarse-grained soil and other bulk granular materials, and when it is more than this broken value, the initial void radio and the dilatancy effects on the strength of the impact will be significantly weakened, and the particle breakage will gradually become the dominant factor affecting the strength.

All information, involving geometry, material, manufacturing, fabrication, installation, ERP data requirements and so on, are embedded in these 3D objects for the purpose of parametric modeling and subsequent data output. 3D solid model acts as the kernel of the system.
The model comprises all detailing information, such as geometry, material, strength, fabrication, installation etc. 2D drawings and raw data for ERP system are automatically created based on the 3D digital model.
Based on the 3D detailing model, the system automatically produces detailing drawings, ERP raw data, joint calculation document and material list.

In the first stage, the ceramic materials receive the initial impact of the bullet and destroy the head of the projectile.
To simulate the three different materials: steel, ceramic and UHMWPE, three different material constitutive models was utilized.
The error comes mainly form the propellant powder control and the mechanical properties of the materials.

Introduction Several research teams from various science research centers and universities from around the world devote their attention to the high-performance concrete area based on the Portland cement.
These high utility materials have also disadvantages for example low fire resistance, especially when silica aggregates is used.
From these reasons is necessary to protect their surface by secondary cladding from refractory materials or other special technology.
