Small Punch Test (SPT) is used to determine current values of basic mechanical properties from a tiny piece of material. This non-standard type of test is preferred if th [...]

Comparison of accumulated damage field of coupled and uncoupled ductile damage models together with history of variables used in calibration process is presented in this [...]

The paper deals with application of selected criteria of ductile fracture to prediction of material damage during the production of bolts by cold forming. Two basic steps [...]

Rod cutting is an important phase of many technological procedures, which includes fast dynamic process of ductile material fracture. Explicit FE solvers seem to be the b [...]

This paper is concerned with numerical simulation of long products’ leveling. The main goal is estimating useful setting of leveling machine to minimize curvature of pa [...]

The stabilized hysteresis loop was determined for the material of railway wheel, by the condition of steady amplitude of axial strain. The compressive test by laboratory [...]

The paper studies how wheel and rail unevennesses effect behaviour and life of wheel-rail system. Unevenness can be caused by the production inaccuracy or by the wear. To [...]

An important phase of the bolt production is a bolt head trimming. It is a very fast, complicated process including material failure. For this type of problems the explic [...]

The paper deals with cooling of grooved roll. The aim is to find optimal spray parameters, specify nozzle type, geometrical configuration and feeding pressure to elongate [...]

The paper deals with problems of buckling in resistors of electric rail vehicles. The resistors are objects in that the electric power is expended during dynamic braking [...]
