A uniaxial high-temperature tensile test of an AA7075 aluminum alloy sheet was conducted using established induction heating system. Five different types specimens were designed to obtain the stress–strain curves at forming temperatures and strain rates so as construct modify Johnson–Cook constitutive model. The stress states numerically simulated ABAQUS finite element software, triaxiality equ...

The goal of the paper is to study limiting behavior Weierstrass measures on a smooth curve genus $g \geqslant 2$ as approaches certain nodal stable represented by point in Deligne–Mumford compactification $\overline{\mathcal{M}}_g$ moduli $\mathcal{M}_g$, including irreducible ones or those compact type. As consequence, rational at boundary $\mathcal{M}_g$ are completely determined. In process,...

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...
