Nodal integration of meshless methods

, 2009
Meshless methods offer interesting properties for the simulation of bulk forming processes. This research concerns the investigation of the stabilized conforming nodal integration scheme (SCNI) for use in metal-forming processes. Two tests are carried out. Firstly, the performance of SCNI is compared to a standard integration scheme.

Projection methods for nonlinear nodal problems

Rocky Mountain Journal of Mathematics, 1977
The work produces some degree-theoretic and operator-theoretic tools for the study of projection methods associated with nonlinear nodal problems. The numerical procedure is outlined for the case of sublinear and superlinear nodal problems.

Modified CEL method for determination of defect formation mechanism in underwater stationary shoulder FSW based on softened pressure-overclosure contact relationship

Forces in Mechanics
The Coupled Eulerian-Lagrangian (CEL) method was employed to simulate underwater friction stir welding with a stationary shoulder tool (USSFSW). The governing equations in the CEL method were formulated for FSW based on the immersed boundary method.
