Quasi-static study on the fluid and structure interactions of the subsurface safety valves (SSSV) for extreme high pressure and high temperature (XHPHT) applications
This thesis summarizes the preliminary design work of a new subsurface safety valve (SSSV) for extreme high pressure (30,000 psi) and high temperature (450°F) (XHPHT) applications. Current SSSV designs are not reliable ...
Finite Element Nonlocal Technique Based on Superconvergent Patch Second Derivative Recovery
This dissertation proposes a finite element procedure for evaluating the high order strain derivatives in nonlocal computational mechanics. The superconvergent second derivative recovery methods used are proven to be ...
