構造用木材の二面せん断試験片を用いた衝撃せん断試験

抄録

In this research, the effect of strain rate on the shear strength of cryptomeria and Japanese cypress in the longitudinal direction was investigated experimentally by using double shear face specimen at room temperature. A screw gear type universal testing machine and sprit Hopkinson pressure bar (SHPB) testing machine were used for quasi-static and dynamic shear tests, respectively. It was found that there is almost no effect of strain rate on the shear strength of both wood materials at least in the rage of strain rate from 10^-3 to 10³ s^-1.
