Understanding the effect of thermomechanical loads during finish cutting processes, in our case hard milling, on surface integrity workpiece is crucial for creation defined quality characteristics high-performance components. Compared to computationally generated modifications by simulation, measurement-based determination material can only be carried out selectively and a point-by-point basis....

Thermal properties of machined materials, which depend significantly on the change in cutting temperature, have a considerable effect thermal machining characteristics. Therefore, used for numerical simulation process should be determined depending temperature. To determine methodology and software-implemented algorithm were developed their calculation. This is based analytical models determina...

This is a study to investigate ballistics performance of armor structures with in-layer deflector against projectiles. For this purpose, the structure, which consists v-cross section sheet metal array covered aluminum and steel plates, has been designed optimized. Firstly, numerical simulations were studied using finite-element method (FEM). The ANSYS LS-DYNA FE software used for ballistic anal...

Finite Element Analysis (FEA) based techniques have become increasingly available to simulate metal cutting process and offer several advantages including prediction of tool forces, distribution of stresses and temperatures, estimation of tool wear, optimization of cutting conditions, tool edge geometry and coatings, and determination of residual stresses on machined surfaces. However, accuracy...

An explicit 3D Finite Element (FE) model was developed in the LS-Dyna code to simulate laser shock paint stripping on aircraft aluminum substrates. The main objective of is explain physical mechanisms process terms wave propagation, stress and strain evolution shape size evaluate effects material parameters pattern. To behavior aluminum, Johnson–Cook plasticity Gruneisen equation state were app...
