AB  - The straight sections of steel pipes are subjected to accumulated loads over the course of their service life, which in most cases are highly damaging. Under ambient temperature conditions, the proposed reinforcement to improve the strength of these structures by thermal agitation in A510AP grade steel bends (used in the manufacture of LPG gas tanks and pipes) under mechanical behavior and different bending moment loads, opening and closing, was studied in this work by FEM, and by using the numerical calculation code ABAQUS as well as the XFEM technique with solid elements as structure, our objective is to evaluate the effect of loading mode, internal pressure level, thermal agitation surface and time of this agitation which is expressed by the graduation exponents of the HAZ in the tubular structure in a steel bend under mixed pressure and moment loading. Numerical damage results are presented in the form of moment-rotation curves. They illustrate the variation in damage as a function of these simultaneously acting effects.
