Failure modes include tensile spall, impact-induced dynamic shear, shock compaction and stea... D Grady - Aps Meeting 被引量: 0发表: 2016年 The Unifying Role of Dissipative Action in the Dynamic Failure of Solids Dissipative action, the product of dissipation energy and transport time, is ...
The phase-field model has proven a promising tool to simulate crack propagation, and special attention has recently been paid to the prediction of crack nucleation. Dynamic shear banding (or the so-called adiabatic shear banding) is a significant ductile failure mechanism in metals and alloys ...
power setting and the gap between the top and bottom sheets affected the quasi-static strength and the fatigue life of the joints. Kapustka et al. [8] investigated the effects of manufacturing variations on the quasi-static and dynamic strengths of DP780, DP980, and TRIP780 single lap-...
pressing adiabatically the mixture of explosive material and air due to a pressure impulse generated by the electric spark of the electrode laid in the shock tube, detonation wave of the shock tube, detonation of detonator, etc. [3–7]. Upon initiation, the pressure of an incoming impulse cau...
Structure of solids and liquidsAbstract We study collective modes in a classical system of particles with repulsive inverse-power-law (IPL) interactions in the fluid phase, near the fluid-solid coexistence (IPL melts). The IPL exponent is varied from n = 10 to n = 100 to mimic the transiti...
Fast Fourier transform (FFT) theory is used to analyze the tensile stress-strain curves of coated fabric membrane materials (PVDF) at high strain rates (350/s, 500/s, 750/s, 900/s and 950/s). The transformation results are extended to characterize the failure and dynamic response of Ferra...
Discussion The short duration, audible high slip velocity events are manifestations of dynamic instability and represent laboratory analogues of regular, fast earthquakes11. Likewise, we posit that the observed spectrum of slow to fast stick–slip events in our experiments are representative of the ...

Analysis of a brittle-ductile transition under dynamic shear loading The competition between brittle and ductile modes of failure is analyzed in a double edge-cracked specimen impacted by a projectile on the cracked side. Fu... A Needleman,V Tvergaard - 《International Journal of Solids & ...
Various types of phenomenological constitutive models are widely used in structural scale computations for prediction of behavior in static or dynamic cases [27], [28]. In adopting to the case of a complex loading program, these models require choice of the elaborate and equally complex criterion....
