Aim & Scope

The aim of Multi-Scale and Multi-Physics Mechanics is to provide a platform for publication of research results in which multi-scale and multi-physics mechanics play a vital role. This journal publishes articles with contributions in all aspects of multi-scale and multi-physics problems. The problems of multi-scale mechanics include structural, mechanical or material systems with varying length or time scales. The problems of multi-physics mechanics involve multiple physical models or multiple physical phenomena.. The scope of Multi-Scale and Multi-Physics Mechanics covers a wide range of themes associated with multi-scale and multi-physics mechanics encountered in engineering and scientific research and practice. Typical subjects considered by the journal include: Analytical, computational, and experimental methods for multi-scale and multiphysics mechanics Multi-scale problems Multi-physics problems Computational materials science and engineering Coupled mechanics MEMS and NEMS Mechanics and materials Mechanics and biology Other related topics

    The formation of silicon-on-nothing (SON) structure during an annealing process from the silicon substrate including the trench structures has been considered as an effective technique to construct the structure that has an empty space under the closed flat surface. Previous studies have demonstrated the mechanism of the formation of SON structure, which is based on the surface diffusion driven by the minimization of their surface energy. Also, it has been fragmentarily shown that the morphology of SON structure can be affected by the initial design of trench (e.g., size, number) and the annealing conditions (e.g., temperature, pressure). Based on the previous studies, here, we report a comprehensive study for the design of the cavity-embedded structure (i.e., SON structure). To do this, a dynamic model has been developed with the phase field approach. The simulation results represent that the morphology of SON structures could be detailedly designed, for example the position and thickness of cavity, the thickness of top and bottom layer, according to the design parameters. This study will give us an advantage in the effective design of SON structures.

    The longitudinal velocity (forward speed) having significant importance in proper running of railway wheelset on track, depends greatly upon the adhesion ratio and creep analysis by implementation of suitable dynamic system on contamination. The wet track condition causes slip and slide of vehicle on railway tracking, whereas high speed may also increase slip and skidding to severe wear and deterioration of mechanical parts. The basic aim of this research is to design appropriate model aimed estimator that can be used to control railway vehicle forward velocity to avoid slip. For the filtration of disturbance procured during running of vehicle, the kalman filter is applied to estimate the actual signal on preferered samples of creep co-efficient for observing the applied attitude of noise. Thus error level is detected on higher and lower co-efficient of creep to analyze adhesion to avoid slip and sliding. The skidding is usually occurred due to higher forward speed owing to procured disturbance. This paper guides to minimize the noise and error based upon creep coefficient.
