内容摘要:
This talk proposes and analyzes a robust C? interior penalty method for a gradient-elastic Kirchhoff plate (GEKP) model on polygonal domains, simulating deformation at the nanoscale. The method combines triangular Hermite elements with a C? interior penalty formulation. After establishing a robust regularity estimate for the model, we derive local lower bounds for a posteriori error analysis. These, along with an enriching operator and its error estimates, yield a Cea-type lemma and consequent optimal error estimates that are robust with respect to a small parameter. Notably, convergence is proved without extra regularity assumptions on the exact solution. Numerical results are included. This is a joint work with Mingqing Chen and Xuehai Huang.
