Abstract

Nowadays, the finite element analyses provide beneficial support in many fields of engineering by means of their cost, time and capacity saving characteristics. During the analyses, the one of the key elements is the correctly defined material properties. This is especially true for the plastics due to their orthotropic and nonlinear material properties as plasticity, relaxation or creep for example. Additionally, the applications of the plastics are widely spread in the automotive engineering beside the other sectors of the industry. Hence, the main goal of the present research is to verify static structural and to validate impact dynamic simulation results by the available material data and actually performed measurement results respectively. Tensile test and creep simulations were carried out in Ansys Workbench software for comparing the static structural simulation results with the available material data given by the material manufacturer in case of the used test samples, boundary conditions and material properties. Following the verification, the material models were applied for a specimen and for a model of an existing product in order to complete validation of the explicit dynamic simulation’s results. Real vertical hammer tests were set up and performed for this purpose and the same procedure was simulated also in order to be able to compare the results and drawn conclusions about the accuracy of the calculation method.

Abstract

"jats:p"A current worldwide economy problem includes both the responsible management of the planet's non-renewable resources and the waste management. The benefits of using recyclable materials and recycling technologies with asphalt mixtures consist mainly of reducing fuel consumption and greenhouse gas emissions. It is well known that oil (from which bitumen is obtained) is a non-renewable resource, hence the its price increase. Therefore, at present, the world is looking for solutions that will lead to a better use of natural resources and to an economic integration of sub-products from various industries. This paper intends to raise awareness of the possibilities for asphalt mixtures recycling and of the recyclable materials that can be used as additives with benefits of each. Document type: Article
