Numerical simulation of damage evolution and mechanical properties for ductile materials

The paper presents results of a numerical modelling of ductile fracture and failure of elements made of 5182H111 aluminum alloy steel subjected to dynamic traction. The analysis was performed using Johnson-Cook model based ABAQUS software. The aim of the research was to specify and test the mechanical properties during numerical simulations. The experimental test results for the mechanical properties of the studies steel are presented with a large description of the testing facilities. The test results were used to determine the temperature dependencies of the mechanical properties, yield strength, modulus of elasticity and thermal elongation

Thermal-Mechanical Coupled Manufacturing Simulation in Heterogeneous Materials

This work is aimed to investigate on thermal and thermo-mechanical behaviour of 6061 Aluminium alloy. The main target of the present investigation is to apply a numerical procedure to assess the thermo-mechanical damage. Finite element analyses of the notched tensile specimens at high temperature have been carried out using ABAQUS Software. The objective was to study the combined effects of thermal and mechanical loads on the strength and ductility of the material. The performance of the proposed model is in general good and it is believed that the presented results and experimental–numerical calibration procedure can be used in practical finite-element simulation
