Lévy flight trajectory-based whale optimization algorithm for engineering optimization
Yongquan Zhou, Ying Ling, Qifang LuoThis paper aims to represent an improved whale optimization algorithm (WOA) based on a Lévy flight trajectory and called the LWOA algorithm to solve engineering optimization…
MLS based local approximation in numerical manifold method
Yuanqiang Chen, H. Zheng, Wei Li, Shan LinThe purpose of this paper is to propose a new three-node triangular element in the framework of the numerical manifold method (NMM), which is designated by Trig3-MLScns.
Well-flow behavior of reorientation fracture considering permeability anisotropy
Xiaoming Tian, Pingchuan DongIn petroleum industry, hydraulic fracturing is essential to enhance oil productivity. The hydraulic fractures are usually generated in the process of hydraulic fracturing…
Evidential uncertainty quantification of the Park–Ang damage model in performance based design
Hesheng Tang, Dawei Li, Lixin Deng, Songtao XueThis paper aims to develop a comprehensive uncertainty quantification method using evidence theory for Park–Ang damage index-based performance design in which epistemic…
Influence of velocity head on filling transients in a branched pipeline
Ling Wang, Fujun Wang, Bryan William Karney, Ahmad Malekpour, Zhengwei WangThe velocity head is usually neglected in the energy equation for a pipeline junction when one-dimensional (1D) hydraulic transient flow is solved by method of characteristics…
Variable-fidelity shape optimization of dual-rotor wind turbines
Andrew Thelen, Leifur Leifsson, Anupam Sharma, Slawomir KozielDual-rotor wind turbines (DRWTs) are a novel type of wind turbines that can capture more power than their single-rotor counterparts. Because their surrounding flow fields are…
High-performance unsymmetric 3-node triangular membrane element with drilling DOFs can correctly undertake in-plane moments
Yan Shang, Song Cen, Zheng-Hua Qian, Chenfeng LiThis paper aims to propose a simple but robust three-node triangular membrane element with rational drilling DOFs for efficiently analyzing plane problems.
3D tolerance modeling and geometric precision analysis of plane features for flexible parts
Xiaokai Mu, Qingchao Sun, Wei Sun, Yunlong Wang, Chuanhua Wang, Xiaobang WangThe traditional precision design only takes the influence of geometric tolerance of the parts and does not involve the load deformation in the assembly process. This paper aims to…
A dynamic simplified Lund model for large-eddy simulation and its application to a centrifugal pump
Xianbei Huang, Baoyun Qiu, Qiang Guo, Zhuqing Liu, Wei Yang, Yaojun LiConstruct a new sub-grid scale (SGS) model which can improve the efficiency and maintain comparative accuracy comparing to the existing dynamic cubic non-linear SGS model (DCNM).
Establishment and verification of a contact model of flowing fresh concrete
Yuan Zhao, Zhennan Han, Yali Ma, Qianqian ZhangThe purpose of this paper is to establish a new dynamic coupled discrete-element contact model used for investigating fresh concrete with different grades and different motion…
Using ensemble Kalman filter to determine parameters for computational crowd dynamics simulations
Fumiya Togashi, Takashi Misaka, Rainald Löhner, Shigeru ObayashiIt is of paramount importance to ensure safe and fast evacuation routes in cities in case of natural disasters, environmental accidents or acts of terrorism. The same applies to…
Numerical study on the perforation of steel plates by multiple projectiles
Yihua Xiao, Huanghuang Dong, Haifei Zhan, Aihua ZhuMetal plates are usually used as protective shields of engineering structures, which probably undergo multiple projectile impacts resulting from gunshot and blast. Though a large…
