...Saibal Kanchan Barik; R. Ganesh Narayanan; Niranjan Sahoo Selection of flow stress models and fracture models to model sheet deformation at high strain rates is of great concern. The same is attempted in the present work during shock tube impact forming of 1-mm-thick AA 5052-H32 sheet using a rigid...

... the sheet at different velocities. Here, the main objective is to understand the effect of flow stress models and fracture models on the forming outputs. The experimental situation is modeled in two stages, i.e., incorporating the pressure in the first stage and displacement of the striker in the second...

The Gent constitutive model for the stress–stretch response has been shown to provide a nearly equivalent rubber elastic behavior as that of the widely used eight-chain model. By combining the simpler stress–stretch relationship from...

.... This analysis is followed and continued by a proper sintering model based on an elastic-viscous analogy that predicts the resulting local densities after sintering and also associated defects. So, from the two subsequent models, it becomes possible to get the final powder densities after processing...
