two-layer metallic sheets have wide applications in aerospace, marine, automotive and domestic industries due to their superlative characteristics. in this paper, the formability of two-layer sheet is investigated through analytical, experimental and numerical approaches. an analytical model is developed based on marciniak-kuczynski method associated hill’s non-quadratic yield criterion. formin...
In this article, the effect of different yield functions on prediction of forming limit curve (FLC) for aluminum sheet is studied. Due to importance of FLC in sheet metal forming, concentration on effective parameters must be considered exactly in order to have better theoretical prediction comparing experimental results. Yield function is one of the factors which are improved by adding new coe...
Advanced composite materials are attractive in situations where high performance materials are required, such as in aerospace, military, medical applications and sporting goods industries. However, because they are difficult to shape into complex geometries, currently, most composite parts are manufactured by the hand lay-up process, which is time-consuming and labor-intensive. The main motivat...
