Abstract: The traditional extended finite-element method (XFEM) encounters some challenges in the problems of frictional contact because the contact forces acting on the interface of cracks are difficult to determine. In this paper, ...

Abstract: Use of a ballast is still popular in railway engineering due to its resilience, relatively low noise, and convenience in construction and maintenance. The ballast layer was modeled with two modeling approaches in this ...

Abstract: Gap shape is an important factor affecting the tandem cascade performance. This paper uses the gap expansion angle (Kb−b) to define gap shape and studies the effect of Kb−b on the two-dimensional flow field and flow ...

Abstract: Effect of airflow managements on the efficiency index of a small container data center having overhead air supply is reported in this study. Seventeen arrangements and configurations regarding the airflow and blockage ...

Abstract: In this work, an easy and low-temperature fabrication method of three-dimensional (3D) ceramic substrate was proposed. A 3DPC ceramic substrate was fabricated by molding alkali-activated aluminosilicate cement (AAAC) to ...

Abstract: Using a flexible asphalt pavement structure with a graded crushed stone base is an effective means to solve reflection cracking, which frequently occurs in the semi-rigid asphalt pavements in Xinjiang. Control indicators ...
