Determination of material properties of moulded GRP moulded connector using a "short" tensile coupon

Cam fiber takviyeli plastik (CTP) yapı elemanları kalıplanarak üretilmekte ve birçok inşaat mühendisliği alanındaki kullanımı giderek artmaktadır. Nümerik analizler ve dizaynlar için bu malzemelerin mekanik özelliklerinin bilinmesi gerekir. GRP birleştirici yapı elemanlarının varsayılan izotropik elastik özelliklerini deneysel olarak belirlemek için yakın zamanda geliştirilmiş olan kısa kupon kullanıldı. Uygun nümerik modellerin kullanımı için lineer olmayan gerilme-uzama modelleri belirlendi. Üretim ve kalıplama şeklinin malzemenin elastik özelliklerine etkisi araştırıldı.

Kalıplanmış CTP birleştiricinin malzeme özelliklerinin kısa çekme kuponu ile belirlenmesi

Glass fibre reinforced plastic (GRP) structural members are manufactured by moulding and are used in an increasing number of civil engineering applications. Measurement of the mechanical properties of these materials are necessary for numerical structural analysis and design. To characterise the isotropic (assumed) elastic properties of the GRP connector, an experimental investigation has been carried out using recently developed "short" coupon. A non-linear stress-strain model is established for use in the appropriate numerical models. Influence of manufacturing and moulding process to the material characteristics are investigated.
