DEIM-embedded hybrid snapshot simulation for reduced order model generation

Feng Bai, Yi Wang

The purpose of this paper is to establish an intelligent framework to generate the data representatives in snapshot simulation in order to construct the online reduced-order model…

Acceleration of structural topology optimization using symmetric element-by-element strategy for unstructured meshes on GPU

Shashi Kant Ratnakar, Utpal Kiran, Deepak Sharma

Structural topology optimization is computationally expensive due to the involvement of high-resolution mesh and repetitive use of finite element analysis (FEA) for computing the…

An improved generalized plasticity model for rockfill materials and its experimental and numerical verification

Xiang-Nan Wang, Yi-Zhao Gao, Xiang-Tao Zhang, Yu-Zhen Yu, He Lv

The stress–strain behaviors of rockfill materials in dams are significantly affected by the anisotropy and grain crushing. However, these factors are rarely considered in…

Car-following traffic model based on PID control: modelling and simulation

Shuang Han, Jing Zhang, Quanyue Yang, Zijian Yuan, Shubin Li, Fengying Cui, Chuntang Zhang, Tao Wang

The performance of the classical car-following system is easily affected by external disturbances. To enhance the performance of the classical car-following model under sudden…

Dual bilinear cohesive zone model-based fluid-driven propagation of multiscale tensile and shear fractures in tight reservoir

Yongliang Wang, Xin Zhang

Hydrofracturing technology has been widely used in tight oil and gas reservoir exploitation, and the fracture network formed by fracturing is crucial to determining the resources…

Reconstruction of a potential coefficient in the Rayleigh–Love equation with non-classical boundary condition

M.J. Huntul, Mohammad Tamsir

The purpose of this paper is to reconstruct the potential numerically in the fourth-order Rayleigh–Love equation with boundary and nonclassical boundary conditions, from…
