Objectives
Students should be able to identify particular aspects of mechanics of solid polymeric materials, namely viscoelastic behaviors, relating them with physical-chemical characteristics of the materials. They should also be able to interpret results from typical mechanical tests and explore its implications at an industrial level, in terms of product design and quality control
