Summary In this paper, we lay out a variational framework for correspondence‐based peridynamic (PD) formulations of solid mechanics. Using the framework, address numerical instabilities original version PD by developing natural stabilization technique that avoids costly bond‐associated approaches and retains structure method with nodal integration. Accuracy, robustness, efficiency proposed naturally stabilized are demonstrated on several computational test cases ranging from linear...
This paper investigates the influence of concrete/gypsum bedding layers and their orientation angles on tensile failure mechanism in three-point bending test based experiments numerical simulations. Rectangular samples containing different combinations concrete gypsum were prepared, i.e. one layer concrete, two concrete. In each configuration, varied between 0° 90° with increment 30°. A total 36 specimens including 12 configurations prepared tested. addition, simulations conducted at 0°,...
The pertrubation decay technique has been recently applied to probe granular material dynamic response under high-rate shear deformations. A vast majority of the simulations this experiment, however, only considered bulk materials and neglected grain-scale phenomena such as grain-to-grain contact friction, well fracture. Mesoscale modeling can be used address these shortcomings. We utilize a peridynamic framework explicitly model each individual particle between them, in addition considering...

We can run simulations faster more efficiently by using parallel processing on these clusters. In this study, we developed version an in-house comprehensive chemical flooding reservoir simulator called...
