Surface wave scattering analysis in an initially stressed stratified media

Anand Mandi, Santimoy Kundu, Prakash Chandra Pal

The present discussed problem deals with the torsional surface wave scattering in an initially stressed inhomogeneous medium. The assumed model consists of tri-mediums resting…

Improvement of a topological level-set approach to find optimal topology by considering body forces

Meisam Takalloozadeh, Gil Ho Yoon

Body forces are always applied to structures in the form of the weight of materials. In some cases, they can be neglected in comparison with other applied forces. Nevertheless…

Hermite polynomial normal transformation for structural reliability analysis

Jinsheng Wang, Muhannad Aldosary, Song Cen, Chenfeng Li

Normal transformation is often required in structural reliability analysis to convert the non-normal random variables into independent standard normal variables. The existing…

Extension of the unsymmetric 8-node hexahedral solid element US-ATFH8 to geometrically nonlinear analysis

Zhi Li, Song Cen, Chenfeng Li

The purpose of this paper is to extend a recent unsymmetric 8-node, 24-DOF hexahedral solid element US-ATFH8 with high distortion tolerance, which uses the analytical solutions of…

Adaptive memory red deer algorithm for cross-dock truck scheduling with products time window

Binghai Zhou, Shi Zong

The cross-docking strategy has a significant influence on supply chain and logistics efficiency. This paper aims to investigate the most suitable and efficient way to schedule the…

Dual-rail–guided vehicle scheduling in an automated storage and retrieval system with loading and collision-avoidance constraints

Changpu Ma, Binghai Zhou

The use of multiple-capacity rail-guided vehicles (RGVs) has made automated storage and retrieval system (AS/RS) optimization more complex. The paper performs dual-RGV scheduling…
