Abstract

A simplified procedure can calculate collapse stresses on a flawed rectangular beam for combined tension and bending. The results obtained are as follows:
(1) The method enables us to calculate the collapse stresses for any flaw size and any combination of tension and bending.
(2) The method leads to an allowable flaw size of about one-tenth the beam width.
(3) The method gives the evaluation of safe side for the experimental result in the case that the defect size⁄beam width ratio is 0. 6.
