Description
  • Bylo studováno šíření napěťové vlny v ocelové tyči podpírané dřevěným blokem. Nejdříve byla provedena numerická simulace problému pomocí LS DYNA 3D. Dřevo bylo uvažována jako ortotropní materiál. Čelo bloku, které bylo v kontaktu s tyčí bylo zvoleno tak, aby bylo kolmé k rovinám L, R a T. Hodnoceno bylo 6 různých druhů dřev. Koeficienty napěťového pulzu byly srovnány s koeficienty stanovenými pro polonekonečnou tyč. Numerické simulace byly podpořeny experimenty provedenými se smrkovým dřevem. Sledován byl také vliv geometrie bloku. (cs)
  • The problem of stress propagation in the steel bar which is supported by a wood block is studied. First of all the numerical simulation has been performed using of LS DYNA 3D finite element code. The wood has been taken as an orthotropic continuum . The face of the block which is in contact with the bar has been subsequently chosen to be normal to L,R and T . The main attention has been focused on the evaluation of the reflection coefficient of the stress pulse at the interface between the rod and the wood block. Six different woods has been considered. These coefficients have been compared with the coefficients determined for the two semi - infinite rods . The results of numerical computation have been strengthened by the experiment performed with the blocks made from spruce wood. The influence of the block geometry on the reflection coefficient has been also studied
