该方法基于“荷载/挠度”曲线中给出的荷载比例极限和规定变形时的荷载。计算这些荷载下的应力。不包括小型无缺陷木材试件的测试。

This method is based on the load proportional limit and the load at a defined deformation which are given in the "load/deflection" curve. Stresses at these loads are calculated. Testing of small defect-free test pieces of wood is not covered.
