This paper emphasizes the influence of micro mechanisms failure a cellular material on its phenomenological response. Most applications materials comprise compression loading. Thus, study focuses anisotropy in mechanical behavior under cyclic loadings. For this study, Digital Image Correlation (DIC) technique (named Correli) was applied, as well SEM (Scanning Electron Microscopy) images were analyzed. The experimental results are discussed detail for closed-cell rigid poly (vinyl chloride)...
The physical and mechanical properties of polytetrafluorethylene (PTFE) are greatly dependent on the degree crystallinity this is extremely important for modeling PTFE processing which complex costly. Differential scanning calorimetry (DSC) one most techniques determination powder granules sample generally used in analysis. This procedure provides samples with a high surface-to-volume ratio, resulting formation considerable number surface crystalline structures, called warts, along bulk...
Abstract Assessing a full set of mechanical properties is rather complicate task in the case foams, especially if material models must be calibrated with these results. Many issues, for example anisotropy and heterogeneity, influence behavior. This article shows through experimental analyses how microstructure affects different setups it also quantifies degree poly(vinyl chloride) foam. Monotonic cyclic tests were carried out using standard compression specimens non‐standard tensile...
Abstract This paper proposes an approach to defining the path of a curved crack in single‐edge notched specimen with gray level residuals extracted from digital image correlation, followed by calibration parameters cohesive zone model. Only experimental force is used cost function minimized via finite element model updating. The displacement and residual fields allow for validation calibrated parameters. Last, results are confronted those given straight highlight benefits accounting actual path.
Abstract The influence of the cooling rate after melting on crystalline weight fraction pure poly(tetrafluoroethylene) (PTFE) was derived from differential scanning calorimetry tests. Specimens made or filled PTFE were manufactured by isostatic constrained uniaxial cold pressing, up to different values porosity. Dilatometry tests carried out these specimens while imposing various heating–cooling treatments. deformations recorded during strongly depend mode and level compaction. original...
Carbon fiber-reinforced poly-phenylene sulfide laminate coupons were impacted at low-energy in a drop-tower machine and subsequently fatigued four-point bending fixture. The doubly damaged test pieces then hot-press reconsolidated inspected nondestructively by vibrothermography to check their structural integrity. residual mechanical properties of the both as-damaged as-repaired conditions determined compression loading with in-plane strain fields via digital image correlation system....
