An innovative strategy to create equivalent elements for modelling assembly points in joined structures

Maxime Bérot, Julien Malrieu, François Bay

Large structures (e.g. plane, bridge, etc.) often include several hundreds of assembly points. Structural computations often use over-simplistic approximations for these…

A computational method for evaluating the damage in a solder joint of an electronic package subjected to thermal loads

Jonas Johansson, Ilja Belov, Erland Johnson, Peter Leisner

Numerical analysis of characteristics of the wind caused by methane-air explosion

Qi Zhang, Lei Pang, Dachao Lin

The high-velocity wind caused by a methane-air explosion is one of the important hazardous effects in explosion events of coal mines, and, however, until now it has not…

Numerical evaluation of the side wall effect on the flow around a hydrofoil

Min He, Lingli Yuan, Lingjiu Zhou, Jing Yang, Zhengwei Wang

Studies of the three-dimensional flow characteristics during hydrofoil cavitation have shown that the side walls strongly affect the flow field around the hydrofoil. The…
