Single Versus Double Screw Extrusion: Impact on Mechanical Performance and Crack Resistance for a Virgin, Recycled, and Blended Polypropylene

Polymer Engineering &Science, EarlyView.
Schematic overview of the study approach and key findings. ABSTRACT To evaluate the influence of extrusion on material performance, three processing methods, single extrusion (1x Ex), double extrusion (2x Ex), and double screw compounding (C), were investigated for virgin polypropylene (vPP), recycled PP (rPP), and a blend containing 10% rPP (rPP10 ...

Experimental and Numerical Studies on Determination of Indirect Tensile Strength of Rocks

Rock Mechanics and Rock Engineering, 2011
Indirect tension tests using Brisbane tuff Brazilian disc specimens under standard Brazilian jaws and various loading arcs were performed. The standard Brazilian indirect tensile tests caused catastrophic, crushing failure of the disc specimens, rather than the expected tensile splitting failure initiated by a central crack.

Estimating the direct tensile strength of rocks from indirect tests

Arabian Journal of Geosciences, 2021
Within the scope of this study, a series of experimental, numerical and statistical analyses were performed in order to find the coefficients that would allow the accurate determination of the tensile strength values of the rocks. In this context, direct and indirect tensile strength values of 9 different rock types including sedimentary, metamorphic ...

Indirect tensile strength of UHSC reinforced with steel fibres and its correlation with compressive strength

Magazine of Concrete Research, 2017
Ultra-high-strength (UHS) fibre-reinforced concrete (FRC) has a much larger tensile strength than normal concrete and engineers should thus consider the tensile strength as a design parameter. However, in the current design codes, the tensile strength of concrete is not considered a major design parameter.
