Bearing in mind that the wheel sleeves of motor vehicles are exposed to strong dynamic loads, and knowing that these are very responsible parts of the constructions, the need for permanent researches of the influence of certain variables on the process of production of them is imposed. The prepared part which, in this case, is obtained by forging f...

The fracture of a part or element of a construction can also be defined as a macroscopic separation of the material that leads to the loss of a solid body load. The fracture is the end result of plastic deformation and occurs when all the potential of the material in terms of elastic and plastic deformation is exhausted. This is the worst case of e...

Two different system modelling can be distinguished in life cycle assessment: attributional and consequential. Attributional modelling is used to describe the present state of the examined system and is characterised with use of allocation, no substitutions, market average suppliers, and cut-off principle. Consequential modelling is used to describ...
