Study on the dynamics of the double cantilever-beam specimen of decagonal Al-Ni-Co quasicrystals
چکیده انگلیسی
This paper investigated dynamic initiation of crack growth and crack fast propagation for the double cantilever-beam specimen (DCB) of two-dimensional decagonal Al-Ni-Co quasicrystals. The elasto-/hydro-dynamic model for wave propagation and diffusion together with their interaction is adopted. Numerical results of stresses, displacements and dynamic stress intensity factor are obtained by the finite difference method. Dynamic initiation of crack growth and crack fast propagation are discussed in detail in which the latter is a nonlinear problem arising from moving boundary effect, which is in particular explored.
