چکیده
Since the introduction of the material point method to the graphics community, researchers tend to focus on defining the weighting function as a direct relation between a particle and the grid nodes in its immediate vicinity, e.g. a quadratic B-spline function, as shown in Figure 1a. GIMP is another alternative which downgrades the C requirement to C and then uses a convolution to resume the C continuity. We assign an axis aligned range to each particle as in Figure 1b and the general form for the weight is

Elasto-plastic analysis of discontinuous medium using linearly conforming radial point interpolation method
In this paper, the linearly conforming enriched radial basis point interpolation method is implemented for the elasto-plastic analysis of discontinuous medium. The linear conformability of the method is satisfied by the application of stabilized nodal integration and the enrichment of radial basis functions is achieved by the addition of linear polynomial terms. To implement the method for the ...
متن کاملShock Waves Calculated Using Material Point Methods
One of the significant advantages of particle methods is their capability of computing large material deformation without the difficulty of mesh distortion. Often the large deformation of a material is caused by shock loading, therefore accurate calculation of shock waves is important for particle methods. In this work we study the numerical properties of four major versions of the material poi...
متن کاملAuthor's personal copy An evaluation of explicit time integration schemes for use with the generalized interpolation material point method
The stability and accuracy of the generalized interpolation material point (GIMP) Method is measured directly through carefully-formulated manufactured solutions over wide ranges of CFL numbers and mesh sizes. The manufactured solutions are described in detail. The accuracy and stability of several time integration schemes are compared via numerical experiments. The effect of various treatments...
متن کاملThe Generalized Interpolation Material Point Method
The Material Point Method (MPM) discrete solution procedure for computational solid mechanics is generalized using a variational form and a Petrov– Galerkin discretization scheme, resulting in a family of methods named the Generalized Interpolation Material Point (GIMP) methods. The generalization permits identification with aspects of other point or node based discrete solution techniques whic...
