Aj. Mcmillan et al., EFFICIENT CALCULATION OF FORCES AND STRESSES DUE TO TRANSVERSE IMPACTOF POLYCRYSTALLINE GRAPHITE BEAMS, Carbon, 32(5), 1994, pp. 905-909
A new method is described for the calculation of the time-dependent fo
rces and stresses in a polycrystalline graphite beam subjected to tran
sverse impact. Unlike earlier methods, which consider the contact area
to be infinitesimal, the present method takes account of the effect o
f the time-dependent finite contact area, and is therefore more realis
tic. It has the effect of limiting the high-frequency modes of respons
e of the beam, which has the computational advantage of improving the
convergence of the summation for stresses.
