The problem of engineering materials selection in relations to the expected properties

Abstract

Nowadays, in the selection of construction materials the most important thing is the unit price, though more expensive materials are very often replaced by cheap plastic as long as their use provides the durability and safety of the constructions. Even after using a lot of treatments to improve their mechanical, physical, in-use and technological properties, engineering materials sometimes do not meet the expected requirements. Therefore, today's products consist of many components made of different materials conforming to specific functions. The subject of the presentation is to analyze the characteristics of engineering materials and the possibility of their modifications depending on the expected parameters. The presentation also focuses on the selection of materials regarding their strength calculations, working conditions (including the impact of the environment on the part of the design), application of the optimal methods of manufacturing etc.
