Development of a Validated Numerical Model of an Unreinforced T-section Pipe for Large Dams
Abstract This paper reports on the development of a validated numerical model (using 3-D finite element method (FEM)) of an unreinforced T-section pipe. Pipe profiling severely compromises the localized performance of the T-section pipe. The main...
