研究了平行于木材纹理方向胶合的硬木榫钉的破坏荷载。两个简单的理论解，使用线弹性断裂力学/理想塑性和线弹性应力分析，考虑到有限的剪切刚度的粘结线，并与实验结果进行比较。理论表明，粘结线剪切强度是韧性接头的主导强度特性，断裂能是脆性接头的主导强度特性。通过曲线拟合确定了粘结线剪切强度和断裂能。
The failure load of axially loaded hardwood dowels glued-in parallel to the grain direction of the jointed timber parts is considered. Two simple theoretical solutions using linear elastic fracture mechanics/ideal plasticity and linear elastic stress analysis, taking into account the finite shear stiffness of the bond line are, presented and compared with experimental results. Theory shows that bond line shear strength is the governing strength property for ductile joints and fracture energy is the governing strength property for brittle joints. Bond line shear strength and fracture energy are determined by means of curve-fitting.
