Abstract

An extensive series of large deformation crushing tests with spruce wood specimens was conducted Material orientation lateral constraint and loading rate were varied Regarding material orientation a reduction in the softening effect and the general force level was observed with a higher fiberload angle A comparison with characteristics gained by application of Hankinson’s formula showed discrepancies in compression strength and the beginning of the hardening effect Lateral constraint of the specimens caused a multiaxial stress state in the specimens which was quantified with the applied measuring method Further a higher force level compared to specimens without lateral constraint and significant hardening effect at large deformations resulted Thus the influence of a multiaxial stress state on the force level could be determined An increase in the loading rate led to higher force levels at any displacement value and material orientation
