RISEffective Mechanical Properties of Auxetic Materials: Numerical Predictions Using Variational Asymptotic Method Based Homogenization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, the variational asymptotic method (VAM) based homogenization framework is used for the first time to determine the equivalent elastic stiffness tensor of auxetic materials. The proposed method allows the ...
Relating Porosity With Ductility in a Commercial AA7075 Alloy: A Combined Experimental and Numerical Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the effect of porosity on the ductility of as-cast AA7075 (a commercial high-strength aluminum alloy) was investigated. The as-cast material was processed through hot upsetting, and specimens with different ...
