This paper presents numerical simulations of metal machining processes with Eulerian and Total Lagrangian Smoothed Particle Hydrodynamics (SPH). Being a mesh-free method, SPH can conveniently handle large deformation and ...

Significant advances in nanoscale research have enabled the continuous miniaturization of devices. With the reduction in the size of the devices, it is important to identify if the continuum scale methods remain applicable ...

Most of the continuum scale processes, such as fracture, plasticity, etc., trace their origin to atomistic scale phenomena. To gain deeper insights into these processes, one needs to understand the behaviour of materials ...

This paper presents a semianalytical methodology for the nonlinear vibration of a functionally graded microplate under transverse patch loadings. The higher-order shear deformation theory (HSDT) is combined with the modified ...

In this work, we use pseudo-spring-augmented smoothed particle hydrodynamics (SPH) framework to understand how the crack paths differ in edge-cracked plates with inclusions when they are made of functionally graded material ...

Many thermo-mechanical processes, such as thermal expansion and stress relaxation, originate at the atomistic scale. We develop a sequential multiscale approach to study thermally stressed superelastic polyimide to explore ...

A three-dimensional SPH computational framework is presented for modeling fluid–structure interactions with structural deformation and failure. We combine weakly compressible SPH with a pseudo-spring-based SPH solver to ...

The NCHRP 1-37A and NCHRP 1-40D models have been incorporated into the PMED program to predict dynamic modulus (|E*|) of asphalt mixes for Level 2 and Level 3 inputs to design and analyze flexible pavement structures. These ...

The porous structure of fine recycled concrete aggregate (FRCA) affects the properties of concrete and limits its use beyond 30 %. This study aims to improve the quality of concrete prepared with 100 % FRCA. Past work ...

Using fine recycled concrete aggregate (FRCA) is challenging because of the presence of mortar fines in higher quantities. Past studies have reported a few approaches (Presoaking FRCA, surface treatment of FRCA, use of ...
