In recent years, there have been extensive efforts to find the numerical methods for solving problems with interface. The main idea of this work is to introduce an efficient truly meshless method based on the weak form for interface problems. The proposed method combines the direct meshless local Petrov–Galerkin method with the visibility criterion technique to solve the interface problems. It ...

This article investigates the study of Topology Optimization (TO) in 3D elasticity problems to determine optimal topology by applying evolutionary methods Smoothing Evolutionary Structural (SESO), Sequential Element Rejection and Admission (SERA), (ESO). These procedures were implemented MATLAB code as an extension Top3d for SIMP using eight-node hexahedral finite element formulation three-dime...

Abstract Earthquake stress drop Δ σ is related to fault slip via , where μ D and L c denote shear modulus, average slip, dimension. C controlled by the system geometry, characterizes effective stiffness of system, commonly assumed be a constant near 1. We use 3D elastostatic models systematically investigate how burial depth, dip angle, direction. find that decreases with smaller depth value fo...

The rising interest in soft robotics, combined to the increasing applications space industry, leads development of novel lightweight and deployable robotic systems, that could be easily contained a relatively small package deployed when required. main challenges for systems are low force exertion control complexity. In this manuscript, manipulator concept, having inflatable links, is introduced...
