$([30,-30]_2)$ fiber takviyeli tabakalı termoplastik kompozit levhalarda delik-kenar arasında oluşan elasto-plastik gerilmeler

Bu çalışmada fiber takviyeli termoplastik delikli kompozit bir levhanın tek yönde çekmeye maruz kalması durumunda delik çapına bağlı olarak levhalarda delikten kenara kadar meydana gelen artık gerilmeler incelenmiştir. Delik tipi daire olarak ele alınmıştır. Çözüm tekniği olarak sonlu elemanlar metodu kullanılmıştır. Çözümlerde delik yarıçapı r=5, 15, 25 ve tabakalar $([30,-30]_2)$ şeklinde alınarak çözümler yapılmış, sonuçlar tablo ve grafiklerde gösterilmiştir.

In this study, fiber reinforced thermoplastic composite laminated plates with a different hole diameter are subjected to in-plane forces. The hole diameters are chosen as d=10, 30, 50 and the configuration is $([30,-30]_2)$. The residual stresses are found from hole to the edge of the plate. The elasto-plastic numerical solution was carried out by using Finite Elements Technique for some iteration numbers. Residual stresses and expansion of plastic zone have been illustrated in tables and figures.
