Adaptive Remeshing for Cohesive Zone Debonding Simulations

The patent implements dynamic adaptivity that automatically adjusts mesh resolution during the simulation based on the computational solution. The system refines mesh in regions where debonding is active and coarsens it where debonding has completed, transforming the static mesh into a dynamic structure that adapts to the evolving physical state. This resolves the contradiction by providing high accuracy only where and when needed, rather than uniformly across the entire model.

The patent applies non-uniform mesh distribution where different regions of the model have different levels of discretization. Specifically, areas with active debonding mechanics maintain fine mesh resolution to capture local stress and deformation details, while fully debonded regions use coarser mesh to reduce computational burden. This local differentiation resolves the contradiction between overall accuracy and computational efficiency.

The patent employs a feedback mechanism where the computational solution (damage parameters, contact status, released energy) is continuously monitored and used to control mesh adaptation. The system detects regions where debonding is active through damage parameter thresholds and contact element status, then automatically refines mesh in those specific locations. This feedback-driven approach ensures high measurement precision is applied only where physically necessary, reducing overall simulation time.

Instead of applying full mesh refinement uniformly across the entire model, the patent applies partial refinement only to specific regions where debonding mechanics are active. The system identifies these regions through damage parameter criteria and contact status evaluation, then applies refinement selectively. This partial action approach maintains necessary accuracy while avoiding the time loss associated with uniform refinement of the entire model.

The patent implements a self-service adaptive remeshing system where the simulation automatically controls its own mesh resolution based on internal physical state indicators. The system uses damage parameters, contact status, and released energy calculations inherent to the debonding analysis to autonomously determine where mesh refinement is needed, without requiring external intervention or complex user-defined criteria. This self-service approach improves productivity while managing complexity by using the existing physical model variables to drive adaptation.

The patent creates a universal adaptive remeshing framework that can handle multiple debonding scenarios and material behaviors through a single set of criteria-based rules. The same damage parameter thresholds and contact status evaluations apply regardless of the specific debonding case, making the system broadly applicable. This universality improves productivity across different applications while avoiding the complexity of implementing separate specialized remeshing algorithms for each scenario.
