Computer simulation of the load test of an extrusion blow moulded product

The results of compression "top load" test of an extrusion blow moulded container, performed in ANSYS Mechanical software, were presented. The nonuniform wall thickness of the blown product was considered because the thickness distribution was the result of the first step of the simulation in ANSYS Polyflow - the simulation of the product manufacturing by extrusion blow moulding. The hydrostatic pressure factor was taken into account during the "top load" simulation, because such a test is usually done for filled products. It was found that the biggest stress values occur around the inlet as well as in the side walls of the container.
