Processes in Masonry Bodies and the Dynamical Significance of Collapse

摘要: We consider masonry bodies with dissipation of the rate type. Global in time existence and uniqueness weak solutions for arbitrary loads initial conditions is established; this includes which structure collapses. "Safe" "collapse" are distinguished by different behaviors (= processes) at large times. Three situations can arise according to properties equilibrium problem. (i) The problem has a (typically nonunique) solution Sobolev space W1,2 displacements; then each process stabilizes inasmuch as kinetic energy tends 0 L2 distance displacement from set all displacements 0. (ii) no Wl,2 but infimum functional on admissible finite. Then norm oo. This may correspond either collapse or situation when p...
