...Y. W. Kwon; Y. Esmaeili; C. M. Park Because most structures are subjected to transient strain-rate loading, an experimental study was conducted to investigate the stress-strain behaviors of an aluminum alloy undergoing varying strain-rate loading. To this end, uniaxial tensile loading was applied...

... a better knowledge of the welding phenomenon and to minimize the risk of failures. In this work, a detailed analysis has been carried out for predicting the heat flow pattern and stress distribution in an aluminum alloy plate during welding. In this study, the modified double ellipsoidal heat source...

... criterion under nonuniform strain-rate loading conditions. Experiments were conducted to support the proposed failure criterion using aluminum alloy AA3003-H14. This study also investigated the that failure envelops in terms of strain rates and the normalized failure strengths. Furthermore, the effects...

... performance of CFRC wound layer is anisotropic, and the layer arrangement is complexity, so it is difficult for mechanics analysis on a cylinder. Considering that the internal pressure in a cylinder is loaded by the aluminum alloy liner and the CFRC wound layers together, two models are built: The first model...

... fields in a 7075-T6 aluminum alloy (A17075-T6). Results of the FEA modeling were in good agreement with experimental measurements. Effects of applied pressures on the residual stress fields are also presented and discussed as a method of estimating high-pressure waterjet induced compressive stresses...

...Min Ya; Fulong Dai; Jian Lu, Mem. ASME Friction stir welding (FSW) is a newly developed welding technique that can join aluminum alloys of low fusion weldability. The conventional hole-drilling method does not consider the nonuniform in-plane stress around the drilled hole, it is no longer valid...
