Combined mixed convection and radiation in ventilated cavities

A. Raji, M. Hasnaoui

The interaction between mixed convection and thermal radiation in ventilated cavities with gray surfaces has been studied numerically using the Navier‐Stokes equations with the…

On the relation between different parametrizations of finite rotations for shells

Boštjan Brank, Adnan Ibrahimbegovic´

In this work we present interrelations between different finite rotation parametrizations for geometrically exact classical shell models (i.e. models without drilling rotation)…

Adaptive analysis in elastoplasticity based on an enhanced error in constitutive relation

L. Gallimard, J.P. Pelle

Many industrial analyses require the resolution of complex nonlinear problems. For such calculations, error‐controlled adaptive strategies must be used to improve the quality of…

Finite element modelling of heat transfer through permeable cracks in hydrothermal systems with upward throughflow

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

We use the finite element method to model the heat transfer phenomenon through permeable cracks in hydrothermal systems with upward throughflow. Since the finite element method is…

Analysis of Poisson’s ratio for a micropolar elastic rectangular plate using the finite element method

Der‐Uei Yang, Fuang‐Yuan Huang

Based on Eringen’s micropolar elasticity theory (MET), a two‐dimensional finite element formulation including one extra degree of freedom is derived by using a linear triangular…

Stiffness and inertia multicriteria evolutionary structural optimisation

K.A. Proos, G.P. Steven, O.M. Querin, Y.M. Xie

In continuation of the recent development of Evolutionary Structural Optimisation (ESO) applied to the simultaneous objective to maximise the natural frequency and to minimise the…
