Shear Testing of Polypropylene Materials Analysed by Digital Image Correlation and Numerical Simulations
TL;DR: In this article, the distribution of shear strains and strain states (triaxiality) were analyzed for two in-plane shear test fixtures (Iosipescu and V-notched rail), using digital image correlation and numerical simulations.

Low-velocity impact response of injection-moulded polypropylene plates – Part 1: Effects of plate thickness, impact velocity and temperature
TL;DR: In this paper, a low-velocity, low-energy impact response of a mineral and elastomer modified polypropylene was characterized by instrumented falling-weight impact testing of plates with annular clamping.

Low-velocity impact response of injection-moulded polypropylene plates – Part 2: Effects of moulding conditions, striker geometry, clamping, surface texture, weld line and paint
TL;DR: In this paper, the low-velocity, low-energy impact response of a mineral and elastomer modified polypropylene was characterised by instrumented falling-weight impact testing of plates with annular clamping.

Numerical simulation of low-velocity impact loading of a ductile polymer material
TL;DR: In this paper, a linear-elastic-viscoplastic SAMP-1 model was used to simulate impact loading of injection-moulded components, and two load cases were simulated; centrally loaded clamped plates and three-point bending of bars.

TL;DR: In this paper, three-dimensional digital image correlation (3D-DIC) with two cameras and stereo vision was used to determine full-field displacements during uniaxial tensile tests, in order to quantify plastic volumetric strains and to obtain true stress-strain curves.
