چکیده
The modelling of fracture initiation and propagation is a nontrivial problem in computational mechanics. However, it an area that extremely important engineering applications, requiring accurate robust numerical methods can be applied to variety materials. This paper presents the development new approach, which combines material, or configurational, forces material point method (MPM), for finite deformation crack linear elastic solids two dimensions. combination these offers number advantages relating flexibility MPM terms decoupling from grid general nature configurational force theory being applicable across different behaviour. In presented this paper, forms basis mechanical response underlying while provides criterion through post-processing procedure. developed framework benchmark problems 2D. All simulations show good agreement with results literature, demonstrates combined configuration force-material promising tool modelling.

Point-based Dynamic Deformation and Crack Propagation
In this paper, we articulate a novel meshless computational paradigm for the effective modeling, accurate physical simulation, and rapid visualization of solid objects. The uniqueness of our approach is that both the interior and the boundary of our new volumetric representation are point-based, generalizing the powerful and popular method of point-sampled surfaces. We also build the point-base...
متن کاملMaterial Point Method Calculations with Explicit Cracks, Fracture Parameters, and Crack Propagation
A new particle-based method, the material point method (MPM), has recently been extended to handle explicit cracks in a new algorithm called CRAMP or “CRAcks with Material Points.” This new method has several advantages for numerical work on fracture. Compared to finite element analysis, CRAMP can handle cracks with similar algorithmic efficiency, but is better at handling crack surface contact...
متن کاملThree-dimensional Crack Propagation Analysis Using Meshless Point Collocation Method
This paper presents a meshless point collocation method for three-dimensional crack propagation. The meshless point collocation method is based on direct discretization of strong-form governing equations to achieve a truly meshless scheme that does not require mesh structures or a numerical integration procedure. These characteristics of the point collocation method enable the direction of an a...

Green’s function, an analytical approach in inhomogeneous linear differential equations, is the impulse response, which is applied for deriving the wave equation solution in composite materials mediums. This paper investigates the study of SH wave’s transmission influenced by concentrated point source disturbance in piezomagnetic material resting over heterogeneous half-space. Green function ap...
متن کاملAnimation of crack propagation by means of an extended multi-body solver for the material point method
We propose a multi-body solver that extends the Material Point Method (MPM) to simulate cracks in computer animation. We define cracks as the intersection between pieces of bodies created by a pre-fracture process and held together by massless particle constraints (glue particles). These pieces are simulated using a MPM multi-body solver extended by us to efficiently handle N-body collisions. B...
