Some of our latest research efforts are tailored to devise new nodal integration techniques by combining meshfree Galerkin methods with the relatively new numerical technology offered by the Virtual Element Method. Nodal integration schemes formulated in this manner are stable and convergent by construction. In this approach, state variables such as strains, stresses, and other internal variables in nonlinear computations can be stored at the nodes just like the displacements.
