Numerical Modeling of the Recession and Closure of Planar Hydraulic Fractures: Contact‐Based Versus Asymptotic‐Informed Schemes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT We compare two algorithms to simulate the propagation, arrest, recession, and closure of a planar hydraulic fracture, focusing on their ability to capture the physical processes governing fracture recession and closure. The first algorithm is based on a fixed grid with contact detection during recession, while the second is based on a moving ...

Stability and Rheological Characteristics of UHMWPE/Paraffin Oil Thermo‐Reversible Sols, Obtained via Twin Screw Extrusion

Polymer Engineering &Science, EarlyView.
UHMWPE and paraffin oil form stable sols up to 10 wt% polymer concentration during twin screw extrusion. The protective effect of nitrogen gas is evident and more pronounced at high process temperature (> 200°C). ABSTRACT In this study, we produced UH‐PO sols using twin screw extrusion and characterized their thermal and rheological properties to ...

Rheological Characterization of UV and Shear‐Induced Degradation of Poly(Ethylene Terephthalate): Linking Environmental and Processing Histories to Recyclability

Polymer Engineering &Science, EarlyView.
Schematic representation of PET degradation during environmental exposure (UV, air, water) and mechanical recycling (shear), highlighting the resulting effects on molecular weight and mechanical tensile performance. ABSTRACT Throughout its lifecycle, poly(ethylene terephthalate) (PET) undergoes significant degradation from long‐term ultraviolet (UV ...
