... by Tubing Conveyed Perforation (TCP) operations exhibit a more pronounced intensity. These nonlinear pressure fluctuations generate significant impact loads at the bottom of the perforating gun, which can cause failure of the perforating tubing. A transient nonlinear pressure field model of perforation...

... as well as the eight (8) pressure cycles described in Sec. 2 above. The problem is nonlinear in geometry, boundary conditions, and material. For the geometry, large displacements are imposed. For the boundary conditions, one contact pair of indenter-pipe is present. For the material, the pipe in contact...
