In the case of the multiaxial stress state, it is more difficult to define a criterion for the transition from the elastic to the plastic state. An implicit Eq. (1) is usually defined to specify Simulation process and setting In this paper, two materials, SPCC (JIS G3141) and Al6xxx,...
The material parameters were determined by minimizing the difference between the experimental loads during ring compression test for Al6061-T6 alloy and corresponding FEM predictions. Eideh et al. [18] developed an inverse technique for a quick estimation of yield strength during laser bending process...
6061-T6 Al alloyelectron beam heatingone dimensional stress wave loadingelevated temperaturesAn experimental method is described that has been used to determine the yield strength of 6061-T6 aluminum after extremely short times at elevated temperature. The method combines electron-beam pulse heating and...
Also in [7] for alloy 6061-T6 there is no marked difference in the critical levels of applied stresses for specimens of sheet and bar materials. However, during a study of alloy AMG-6 in [8] it was quite convincingly shown that the critical stress levels corresponding to damage initiation...
In order for demonstration, the heat-treated Al6061-T6 specimens were prepared, and the 0.01% offset yield strengths were estimated by the proposed algorithm to compare with those obtained by the tensile test. Results showed good agreement. This method can be used to evaluate the degradation of...
stress space. The results are significantly different than observed for other metals, especially for aluminum alloys (e.g. Khan et al., 2009). Elastic moduli within each subsequent yield loci are also measured during these experiments with the increase in plastic strain. The observed small ...

For the same stress ratio, the delay period in the 6063-T6 alloy was found to be more than in the 6061-T6 alloy. The experimental results when plotted on log-log graph paper, show that NDNCAL vs overload ratio and crack length (when U = U min ) vs overload ratio fit a straight ...
