Bu çalışma, deneysel ve sayısal olarak kompozit yamalar ile tamir edilen çatlaklı sandviç kirişlerin eğilme darbe davranışını araştırmaktadır. Sandviç kiriş elemanları yüzey tabakaları, cam elyaf takviyeli kompozit, köpük çekirdek, PVC malzeme ve yapıştırıcı tabakalardır. Üst yüzey tabakasına çatlak oluşturularak hasar verilmiştir ve kompozit yama yapıştırılarak tamir edilmiştir. Düşük hızlı darbe davranışı, farklı yama malzemeleri, kalınlıkları ve darbe enerjileri açısından incelenmiştir. Sayısal darbe analizleri, kompozit sandviç kirişin hasar davranışını modellemek ve deneysel darbe testi sonuçlarını karşılaştırmak için yapılmıştır. PYTHON program dili ile parametrik modelleneme yapılmıştır. Sonlu elemanlar alt programı ABAQUS-VUMAT kullanılarak 3B Hashin hasar modelleri kompozit yama ve yüzey tabakalarına uygulanmıştır. Son olarak, hasarlı kirişin eğilme rijitliği yama uygulaması ile artırılmıştır. Sandviç kirişlerin hasar toleransları, temas kuvveti değişimleri, kinetik enerji varyasyonları ve darbe sonrası hasar modları dikkate alınarak farklı yama parametreleri için belirlenmiştir.

This study focused on the flexural impact response of cracked sandwich beams repaired by composite patches experimentally and numerically. The sandwich beam members are face-sheets, glass-fiber reinforced plastic (GFRP) composite material, foam core, PVC material, and adhesive layer. The cracked was created on the surface of the top face-sheet to damage it and it was repaired by bonding external composite patch. Low-velocity impact response was investigated in terms of different patch materials, thicknesses, and impact energies. The impact analysis was performed to model the damage behavior of the composite sandwich beam and to compare experimental impact test results. 3D Hashin damage models were used to obtain damage characteristic of composite laminates with patch application using the explicit finite element subroutine ABAQUS-VUMAT with scripting language via PYTHON programme language. Finally, the bending stiffness of the cracked beam was increased using the patch application. Damage tolerances of sandwich beams were determined for different patch parameters considering contact force variations, kinetic energy variations and after-impact damage modes.
