Abstract
Komposit digunakan untuk pengganti logam, dengan mempertimbangkan kekuatan yang tidak berbeda jauh dengan logam. Glass fiber-reinforced polymer (GFRP) dan carbon fiber-reinforced polymer (CFRP) merupakan dua komposit yang saat ini banyak digunakan. Namun pada penggunaannya komposit dapat mengalami kegagalan. Salah satu kegagalan material komposit adalah delaminasi, yakni lepasnya laminat-laminat antar lapisan (layer) material komposit. Pada penelitian ini, telah dilakukan perbandingan hasil simulasi delaminasi dengan tujuan mencari metode terbaik pada 2 metode berbeda yakni, Cohesive Zone Model (CZM), dan Virtual Crack Closure Technique (VCCT) pada dua material berbeda yakni, carbon fiber-reinforced polymer (CFRP) dan glass fiber-reinforced polymer (GFRP). Simulasi dilakukan menggunakan ANSYS Workbench Mechanical, dimana terlebih dahulu dilakukan analisa mesh sensitivity untuk menentukan ukuran elemen paling optimal, dimana didapat ukuran 0.4 mm merupakan yang paling optimal. Setelah itu dilakukan analisa karakterisasi delaminasi dengan mempelajari kurva stress-strain dan distribusi tegangan-regangan. Dari analisa tersebut, dengan menggunakan parameter, didapat VCCT merupakan metode terbaik karena sesuai dengan teori, memiliki nilai margin error yang rendah, serta tidak memerlukan adanya preparasi delaminasi.

Composites are used for metal substitutes, taking into account the strength that is not much different from the metal. Glass fiber-reinforced polymer (GFRP) and carbon fiber-reinforced polymer (CFRP) are two composites that are currently widely used globally. However, the use of composites can fail. One of the failures of composite materials is delamination, which is the removal of laminates between layers of composite materials. In this study, a comparison of delamination simulation results have been conducted with the aim of finding the best method in 2 different methods namely, Cohesive Zone Model (CZM), and Virtual Crack Closure Technique (VCCT) on two different materials namely, carbon fiber-reinforced polymer (CFRP) and glass fiber-reinforced polymer (GFRP). The simulation is done using ANSYS Workbench Mechanical, where first a mesh sensitivity analysis is performed to determine the most optimal element size, where the 0.4 mm size is the most optimal. After that the delamination characterization is analyzed by studying the stress-strain curve and the stress-strain distribution. From this analysis, using parameters, obtained VCCT is the best method because it is in accordance with the theory, has a low error margin value, and does not require any delamination preparation.
