Three dimensional multi-pass repair weld simulations [PDF]
International Journal of Pressure Vessels and Piping, 2005 Full 3-dimensional (3-D) simulation of multi-pass weld repairs is now feasible and practical given the development of improved analysis tools and significantly greater computer power. This paper presents residual stress results from 3-D finite element (FE) analyses simulating a long (arc length of 62°) and a short (arc length of 20°) repair to a girth ...
