Experimental Study and Numerical Model of Spruce and Teak Wood Strength Properties Under Compressive High Strain Rate Loading

Abstract

The dynamic increase factor phenomenon occurred in both tested materials, soft wood and hard wood, with the stresses rising with an increase of the strain rate.  The dynamic increase factors of spruce wood in the longitudinal, tangential, and radial direction were obtained.  The dynamic increase factors of teak wood in the longitudinal and radial direction were obtained.  The parameters applied in the numerical simulation using LS-Dyna for the SHPB rods, the tested wood materials and the contacts in the experiments conducted were satisfactory.
