In this study, the SDR was in the range of 8–32, and the temperature was in the range of 20–800 °C to investigate the effects of SDR and temperature on the impact response of the structure. The data of the main models are shown in Table 2. Table 2. Part of the model ...
However, material forming involves many more factors than stress states, such as temperature, strain rates, loading directions and paths. Among them, the anisotropic fracture has been pointed out as a dominant factor in deciding both global formability in for example Nakajima tests [[43], [44],...
The effect of stress triaxiality on plastic instability and fracture strain was also examined. The deformation process should be considered as explained, and the anisotropic plastic response induced by the deformation could be introduced in constitutive equations of G'Sell....
The integrity of structural materials is oftentimes defined by their resistance against catastrophic failure through dissipative plastic processes at the crack tip, commonly quantified by the J-integral concept. However, to date the experimental stress a
The results from this model material experimental data and the lattice model predictions are discussed with respect to the role of porosity on the deformation and fracture of quasi-brittle materials.Similar content being viewed by others Investigation of the Effects of Stress Triaxiality and Porosity ...
The stress triaxiality is, besides the strain intensity, the most important factor that controls initiation of ductile fracture. In this study, a series of tests including upsetting tests, shear tests and tensile tests on 2024-T351 aluminum alloy providing clues to fracture ductility for a wide ra...
Because these mechanical properties are not only functions of the exposed temperature, but also the cooling method used, two sets of empirical equations – one for air cooling and the other for water cooling – will be presented. Finally, to account for the effects of heating method used, ...
The plastic deformation and failure behavior of metals is significantly affected by loading conditions such as stress state, strain rate, temperature and etc. In this study, the tensile behavior of a dual-phase Ti-6Al-4V alloy was investigated and the influences of stress triaxiality, strain rate...
