Homogenization effects on simulated pultruded glass fibre reinforced laminate under compression – from static to dynamic models

چکیده
This study presents a numerical analysis of failure in pultruded glass fibre reinforced polymer (GFRP) with three reinforcement layers, subjected to out-of-plane compressive loadings at low and high strain rates (10 -3 s -1 10 3 ). The simulations targets computationally efficient homogenization different element types sizes. A single-element model was created demonstrate the highest level homogenization. material properties homogenized were calculated using ESAComp (Altair) software. 3D Hashin criterion implemented as user-defined subroutine into finite method Abaqus (Simulia/Dassault Systemes) predict failure. comparison between meshes elements shows sufficient accuracy response damage onset, but location crack not accurately predicted expected. High-rate impact Split Hopkinson Pressure Bar tests showed that mesh does significantly affect (strain) by model.

متن کاملDynamic homogenization in periodic fibre reinforced media. Quasi-static limit for SH waves
The effective response of a periodic fibre reinforced material to SH wave propagation is studied using the method of asymptotic homogenization, complex variable theory and multipole expansions. The quasi-static limit of the effective properties is calculated when the wavelength is much longer than the defining lengthscale of the microstructure. The method developed allows the determination of t...

متن کاملFracture behavior of Zr55Cu30Al10Ni5 bulk metallic glass under quasi-static and dynamic compression
Fracture behavior of Zr55Cu30Al10Ni5 bulk metallic glass was investigated under quasi-static compression at strain rate of 10/s using an Instron testing machine and dynamic split Hopkinson bar (SHPB) compression with strain rate of about 1900–4300/s. Pronounced strain softening, especially past the peak stress, was observed under SHPB tests and compared with the distinct flow serrations under q...
