Body force method (BFM) was originally proposed in 1967 as a general technique for the stress analysis of notch and crack problems. The concept of BFM is to express the stress fields of elastic problems by means of superposition of point force solutions. BFM has been provided a number of highly accurate solutions of practical problems by developing special programs suitable for individual problems. In 1990, a versatile program based on BFM for general 2D problems was developed by consideringdoi:10.4028/www.scientific.net/kem.251-252.97 fatcat:fqoagdacwbfwjoixut7uql7vhy
