In this work, the damping caused by an extra layer in layered half-space is considered. Damping layer in the three-layer system has elastic or visco-elastic properties with stiffness about ten times smaller than the stiffness of the other two layers. The problem of propagation of the wave induced by pressure pulse in an infinite elastic half-space layer is modelled as a plane strain case and solved...
W części l pracy zaprezentowano m.in. fenomenologiczną teorię nieustalonego przepływu ciepła z uwzględnieniem przejść fazowych w stali. Podano sposób przygotowania i weryfikacji niezbędnych danych termiczno-metalurgicznych na przykładzie stali 16MnCr5. Dane te wykorzystano w tej części rozprawy. Zastosowano metodę elementów skończonych i program SYSWELD. Punktem wyjścia do obliczeń jest sformułowanie...
Soft tissues mostly exhibit strongly nonlinear behaviour while undergoing large strains. New macroscopic models for both isotropic and transversely isotropic soft tissues have been proposed. The models developed are suitable for finite element formulation. It the first part of the paper isotropic models have been proposed. Implementation in the FEM programme ABAQUS has been discussed. Muscle contraction...
