Using hot aggregates in concrete making results in drop in compressive strength of the produced concrete. Various methods have been proposed for cooling concrete aggregates. In this paper we propose a modified design for ...

A tractor-semitrailer vehicle travelling over a random road surface is modelled using finite element and analytical methods. The vehicle's linear models are constructed in such a way as to describe the bounce and pitch ...

A new method (thermal spokes) has been proposed to simulate the guide roll effect in FE analysis of the ring rolling process. The method is simple to use with existing FE formulations, does not introduce further nonlinearities, ...

Lagrangian and Eulerian finite element formulations have been traditionally used for modeling of the orthogonal metal cutting process. In this paper it is shown that a more general formulation, the arbitrary Lagrangian-Eulerian ...

Two steel surfaces in sliding contact are examined analytically and experimentally. The experiments are restricted to the reciprocating sliding of a relatively hard circular cylinder on a soft plane but the analytical model ...

Spinning of sheet metals into cylindrical cups is an important sheet metal forming process for its advantages of flexible tooling and very small forming loads. The most challenging aspect in this process is its low formability ...
