Experimental and numerical study on progressive damage and failure in composite laminates during open-hole compression tests
نویسندگان
چکیده
Progressive damages in the open-hole compression (OHC) tests of composite laminates were experimentally and numerically studied. In experiment, failure mechanisms investigated via situ microscopy observation, digital image correlation, X-ray radiography, computed tomography. Three layups tested to examine dependence progressive on layups. Additionally, numerical simulation was conducted comprehensively mechanisms. studies, scheme, considering plasticity, kink-band failure, multiple intra-laminar cracks, delamination, developed. From experiment simulation, it is clarified that initiated propagated by combined stress states consisting longitudinal in-plane shear around cracks. Therefore, for high-fidelity OHC various layups, necessary capture interaction between cracks state criteria modeling

Continuum Damage Mechanics Models for the Analysis of Progressive Failure in Open-Hole Tension Laminates
The performance of a state-of-the-art continuum damage mechanics model for interlaminar damage, coupled with a cohesive zone model for delamination is examined for failure prediction of quasi-isotropic open-hole tension laminates. Limitations of continuum representations of intra-ply damage and the effect of mesh orientation on the analysis predictions are discussed. It is shown that accurate p...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
assessing political stability and instability in central asia and caucasus; case study, azerbaijan and kyrgyzstan
منطقه ی آسیای مرکزی وقفقاز به عنوان منطقه ای تاریخی و به دلیل دارا بودن ذخایر عظیم هیدرو کربنی از اهمیت ویژه ای برخوردار است. کشورهای این منطقه از عوامل عمده ی بی ثباتی نظیر عوامل جغرافیایی، اقتصادی، امنیتی، اجتماعی و سیاسی رنج می برند. پس از فروپاشی اتحاد جماهیر شوروی کشورهای منطقه از نعمت استقلال ناخواسته ای برخوردار شدند که مشکلات فوق را برای آن ها چندین برابر می کرد. در این روند برخی از این...
15 صفحه اولDamage and failure in low energy impact of fiber-reinforced polymeric composite laminates
We analyze the damage initiation, damage progression, and failure during 3-dimensional (3-D) elastoplastic deformations of a fiber reinforced polymeric laminated composite impacted by a low speed rigid sphere, and compare computed results with experimental findings available in the literature. Damage is assumed to initiate when one of Hashin’s failure criteria is satisfied, and its evolution is...
متن کاملDamage Assessment of Drilled Hybrid Composite Laminates
Hole drilling operations are common in fibre reinforced plastics FRP’s to facilitate fastener assembly to other parts in more complex structures. As these materials are non-homogeneous, drilling causes some damages, like delamination, for example. Delamination can be reduced by a careful selection of drilling parameters, drill material and drill bit geometry. In this work two types of laminates...
