Using finite strain 3D‐material models in beam and shell elements

Sven Klinkel, Sanjay Govindjee

In this paper an interface is derived between arbitrary three‐dimensional material laws and finite elements which include special stress conditions. The mechanical models…

Efficiency speed‐up strategies for evolutionary computation: an adaptive implementation

Kwong‐Sak Leung, Jian‐Yong Sun, Zong‐Ben Xu

In this paper, a set of safe adaptive genetic algorithms (sGAs) is proposed based on the Splicing/Decomposable encoding scheme and the efficient speed‐up strategies…

Advances in two‐dimensional structural loadflow visualisation

W. Waldman, M. Heller, R. Kaye, F. Rose

In recent years, a novel method for computing loadflow orientations and loadpaths, which is based on iterative solutions of non‐linear equations and finite element…

Numerical simulation of turbulent flow and heat transfer in multi‐channel, narrow‐gap fuel element

Huang Jun, Q.W. Wang, W.Q. Tao

A computational study of convective heat transfer for turbulent flows in multi‐channel, narrow‐gap fuel element has been carried out, using a general marching procedure…

Safety format for the design of concrete frames

António A.R. Henriques, Francisco Calheiros, Joaquim A. Figueiras

A contribution to the definition of a novel safety format for the design of concrete structures based on non‐linear methods of analysis is the main purpose of this work. A…

Finite element modelling of reactive fluids mixing and mineralization in pore‐fluid saturated hydrothermal/sedimentary basins

Chongbin Zhao, Ge Lin, B.E. Hobbs, Yuejun Wang, H.B. Mühlhaus, A. Ord

We present the finite element simulations of reactive mineral‐carrying fluids mixing and mineralization in pore‐fluid saturated hydrothermal/sedimentary basins. In…
