Abstract
The subject of this paper is experimental testing of a polymer and definition of the idealised stress/strain diagram, from which the modulus of elasticity can be easily defined. The analysis was conducted on polymer straps made of ethylene polymer of high density (HDPE). In this case the polyethylene (PE) was produced almost entirely from recycled material and that defines its cost. PE generally has high density and very good mechanical characteristics and resistance to chemicals. As a material it is used in production of reservoirs and containers for various purposes. This paper is trying to define the basic characteristics of polymers by observing their tensile strength, to propose an idealised stress/strain diagram and to define the numerical values of the modulus of elasticity. Also the intention is to create a tool which would enable the definition of the stress / strain diagram for any similar material and broaden the application and use of such types of materials.
