Abstract


Perkembangan teknologi material komposit terutama di material komposit laminat sangat pesat. Material komposit laminat tersusun dari beberapa gabungan lamina-lamina yang berikatan sehingga sering menyebabkan terjadinya deformasi. Salah satu dari model kerusakan kritis pada komposit laminat yaitu delaminasi. Untuk mengetahui proses delaminasi, dimodelkan double centilever beam dengan pembebanan beban berupa displacement. Dalam penelitian ini dilakukan analisa delaminasi laminat terhadap variasi arah serat yaitu [0/+45/+45/0]2s dan [0/+45/+90/-45]2s dengan menggunakan teknik Cohesize Zone Model (CZM) dan Virtual Crack Closure (VCC) menggunakan ANSYS Workbench 19.I dengan modal static structural. Kemudian dilakukan analisa dari hasil simulasi numerik delaminasi pada material sesuai dengan teori. Dengan menggunakan 3750 elemen, 7500 elemen dan 15000 elemen didapatkan hasil bahwa nilai critical force dari variasi [0/+45/+90/-45]2s jauh lebih besar daripada [0/+45/+45/0]2s dan juga dianalisis karakterisasi stress-strain hasil dari simulasi.
