Název v původním jazyce

Reflection of stress pulse at the interface between elastic bar and wood block

Popis výsledku v původním jazyce

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 . Theface 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 theblocks made from spruce wood. The influence of the block geometry on the reflection coefficient has been also studied.
