Abstract
Nonlinear finite element analysis with normal vector constraint that is updated automatically was performed. We created a virtual point cloud of a deformed plate, and triangle polygons. The plate created for constructing normal vector constraint was used as a reference solution. We analyzed another plate that had coarse mesh and different distributed load with normal vector constraint to match the deformation to the reference solution. The accuracy of displacement and Cauchy stress was mostly in good agreement.
