    The files named "Fsweep_NAME", where "NAME" refers to NC45, NG45, CB45, CF45-PARL, CF45-PERP, and BASE, contain frequency-sweep dynamic mechanical analysis (DMA) data acquired at 30 °C for the respective elastomers. Measurements were made in the dual-cantilever mode using a strain amplitude of 0.1%.The files named "Tsweep_NAME" contain temperature-sweep DMA data acquired at a constant heating rate of 3 °C/min, a strain amplitude of 0.1 %, and a strain frequency of 1 Hz.The files named "TENSILE_NAME" contain stress vs. strain data acquired on dumbbell specimens with a gauge length of 20 mm, a width of 2 mm, and a thickness of 2 mm, at a constant extension rate of 500 mm/min. The files named "CYCLIC_TENSILE_NAME" contain stress vs. strain data for these specimens using a triangular strain waveform, consisting of loading and unloading of the dumbbell specimen at a constant displacement rate of 50 mm/min. All the tensile testing data were acquired at room temperature.The files named "LOAD_DISP_NAME" contain normalized load vs. displacement data acquired on SENT specimens, as discussed in ref. 1. The load is normalized by the initial area of the uncracked ligament. The files named "R_CURVE_SENT_NAME" contain R-curve data for the SENT specimens. The normalized strain energy is obtained by dividing the strain energy, U, by the initial area of the uncracked ligament. All the fracture testing data were acquired at room temperature.Reference:1.

    On the merging of turbulent spots in a supersonic boundary-layer flow

    No full text
    The complex transition flow physics associated with the merging of turbulent spots in a Mach 2 boundary-layer has been studied using direct numerical simulation. Dynamics of an isolated turbulent spot, merging of laterally displaced spots, and merging of two spots in tandem are considered. The coherent structures associated with the wingtip region of the spot are found to play a major role in destabilising the surrounding laminar fluid. In the merging of laterally displaced spots a strong velocity defect, resulting in unstable inflectional velocity profiles, is observed in the interaction zone. These local inflectional instabilities within the interaction region trigger new large scale coherent structures. During the inline merging, the calmed region behind the tail of the downstream spot is found to suppress the growth of the upstream spot. The upstream spot is ultimately engulfed by the downstream spot
