...Fan Yafu; Wang Qu-dong; Ning Jun-sheng; Chen Jie; Ji Wei This paper introduces a method to determine the material constants for Johnson–Cook model of an as-extruded Mg–Gd–Y series alloy by quasistatic tests on Instron 1251 and Hopkinson bar experiment at room and elevated temperatures. The results...

...Jia-Liang Le; Zdeněk P. Bažant; Qiang Yu The effect of the size of hybrid metal-composite joint on its nominal strength, experimentally demonstrated in the preceding paper (part I), is modeled mathematically. Fracture initiation from a reentrant corner at the interface of a metallic bar and a fiber...

... can both stretch and bend. The imperfections are in the form of missing bars, misplaced nodes, and wavy cell walls. Their effect on the macroscopic bulk and shear moduli is numerically investigated by considering a unit cell containing randomly distributed imperfections, and with periodic boundary...

... are retained. The reduced system is then specialized to the case of a bar on a frictional surface. For this problem, a second reduction is made by noting that the time derivative of the friction force on the stuck block nearest the slip zone is much greater than the time derivatives of the friction forces...

...Carmen Chicone; Michael Heitzman; Z. C. Feng Exact solutions are obtained for a model of the longitudinal displacement along an elastic tapered bar due to a force applied at its blunt end. A formula for velocity amplification is given; it specifies the velocity of the pointed end of the bar shortly...

... to a system parameter is then presented for structural damage detection. A numerical example with a 31 - bar plane truss structure is used to verify the proposed method with different damage scenarios with or without model error and noise effect. 03 02 2005 03 02 2006 bars supports...

...Herzl Chai A combined experimental∕analytical work is carried out to elucidate the energy absorption potential of laterally confined bars under monotonically increasing edge displacement. The thickness t and length L of the bar, as well as the wall-to-wall separation distance, h...
