RISIncorporation of Dynamic Strain Aging Into a Viscoplastic Self Consistent Model for Predicting the Negative Strain Rate Sensitivity of Hadfield Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new multiscale modeling approach is proposed to predict the contributions of dynamic strain aging (DSA) and the resulting negative strain rate sensitivity (NSRS) on the unusual strainhardening response of Hadfield steel ...
The Precise Determination of the Johnson–Cook Material and Damage Model Parameters and Mechanical Properties of an Aluminum 7068-T651 Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Al 7068-T651 alloy is one of the recently developed materials used mostly in the defense industry due to its high strength, toughness, and low weight compared to steels. The aim of this study is to identify the Johnson–Cook ...
