Prediction of wrinkling initiation in sheet metal forming processes

J.B. Kim, D.Y. Yang

The initiation and growth of wrinkles are influenced by many factors such as stress ratios, the mechanical properties of the sheet material, the geometry of the workpiece, contact…

Friction evolution as a result of roughness in fractal interfaces

E.S. Mistakidis, O.K. Panagouli

In this paper, the influence of fractal interface geometry to the evolution of the friction mechanism is studied. The paper is based on fractal approaches for the modeling of the…

Suboptimal cycle bases for the force method

A. Kaveh, G.R. Roosta

An improvement is presented for the existing minimal cycle basis selection algorithms increasing their efficiency. This consists of reducing the number of cycles to be considered…

Optimising process planning using groups of precedence between operations based on machined volumes

J. Ciurana, G.‐R M.L., R. Castro

In this paper we discuss the problem of defining the manufacturing route taken by parts in terms of their technological features. We look closely at the use of the new computer…

The numerical modelling of ceramics subject to impact using adaptive discrete element techniques

M.G. Cottrell, J. Yu, Z.J. Wei, D.R.J. Owen

In recent years, developments in the field of lightweight armour have been of primary importance to the defence industry. This necessity has led to many organisations adopting…
