On the modeling of large ratcheting strains with large time increments

Göran Johansson, Magnus Ekh

This paper aims to speed up finite element analyses of structures with a highly nonlinear material response subjected to many loading cycles.

A hybrid ant strategy and genetic algorithm to tune the population size for efficient structural optimization

A. Kaveh, M. Shahrouzi

Although genetic algorithm (GA) has already been extended to various types of engineering problems, tuning its parameters is still an interesting field of interest. Some recent…

Analysis and optimization of dynamically loaded porous metal sliding bearings under conditions of elastohydrodynamic lubrication

Aleksandar Marinković, Božidar Rosić, Georgios Petropoulos

This paper aims to develop a simulating model of a journal porous metal bearing under elastohydrodynamic conditions and combined (radial, friction and thermal) load distribution…

Natural neighbour Galerkin computation of the vibration modes of fluid‐structure systems

F. Daneshmand, S. Niroomandi

This paper seeks to extend the application of the natural neighbour Galerkin method to vibration analysis of fluid‐structure interaction problems.

Dynamic response and radial wave propagation velocity in thick hollow cylinder made of functionally graded materials

S.M. Hosseini, M. Akhlaghi, M. Shakeri

This paper seeks to obtain the dynamic behavior of cylinders made of functionally graded materials (FGMs). The cylinder should be analyzed subjected to dynamic and shock loads.
