FEM Implementation of the Coupled Elastoplastic/Damage Model: Failure Prediction of Fiber Reinforced Polymers (FRPs) Composites
The coupled damage/plasticity model for meso-level which is ply-level in case of Uni-Directional (UD) Fiber Reinforced Polymers (FRPs) is implemented. The mathematical formulations, particularly the plasticity part, are discussed in a comprehensive manner. The plastic potential is defined in effective stress space and the damage evolution is based on the theory of irreversible thermodynamics. T...
متن کاملFractography of Polymer Composites: Current Status and Future Issues
With the increasing prevalence of polymer composites in engineering applications, invariably mechanical failures of these components are occurring. Key to addressing this is fractographic analysis; the examination of fracture surfaces to deduce information about the damage and failure of components. The fractography of isotropic materials, particularly metals, has been used as a tool for many y...

15 صفحه اولUsing Fractography to Investigate Causes of Material Failure in Sulfone Polymers
The SEM is especially useful when combined with Energy Dispersive X-ray spectroscopy (EDX), which can be performed in the microscope, enabling very small areas of the sample to be analyzed for their elemental composition. One disadvantage of the SEM approach is related to its high resolution. Only a very small area can be analyzed and the fracture pattern can rapidly become very complex to inte...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
