 Abstract : In this talk, we shall discuss three concurrent multiscale methods, namely, the bridging scalemethod (BSM), the pseudo-spectral multiscale method (PMM), and a finite difference approach(FDA). These methods share the same idea of a sharp domain decomposition. The first twomethods adopt a time history treatment for interfacial conditions, yet with two different waysin the displacement decomposition. The finite difference approach adopts a velocity interfacialcondition instead, which is local in time and hence allows treating solids with relatively strongnonlinearity and large deformation. Numerical results have demonstrated the efficiency andaccuracy for these methods. |
