POLYPROPYLENE TENSILE TEST UNDER DYNAMIC LOADING [PDF]
Journal of KONES. Powertrain and Transport, 2014 In this paper, a testing method is developed to determine the dynamic stress–strain responses of the polypropylene (PP) under high strain rate uniaxial tension conditions. The main objective of this study is to determine the dynamical behaviour of PP materials under transitory loading.

Dynamic loading of electric machines during testing
International Journal of Engineering & Technology, 2018 An energy-efficient and simple method of testing electric motors in a dynamic mode is considered. When testing an electrical machine, the rotor is driven into a reciprocating rotary motion. The source of power of the power converter, which controls the electric machine, is a supercapacitor.
