Abstract
Material komposit saat ini terus berkembang, salah satunya
adalah material komposit laminat. Material komposit laminat
terdiri dari lamina-lamina dimana ikatan yang berdekatan kerap
terdeformasi, yang biasa disebut sebagai delaminasi. Delaminasi
pada material komposit laminat dapat dianalisis menggunakan
metode numerik dimana dalam penelitian ini menggunakan
software yang berbasis elemen hingga, yaitu ANSYS
Mechanical/APDL. Untuk mengetahui proses delaminasi yang
terjadi, double cantilever beam di modelkan dengan pemberian
beban berupa displacement. Variasi penelitain yang digunakan
diantaranya arah serat, letak initial crack, dan panjang initial crack.
Dari hasil simulasi didapatkan bahwa, double cantilever beam
dengan panjang initial crack 30 mm dan arah serat 0o memiliki
reaction force yang paling tinggi, yaitu 116.68 N pada ketebalan
beam yang sama. Double cantilever beam dengan panjang initial
crack 55 mm dan arah serat 90o membutuhkan reaction force yang
paling kecil diantaranya, yaitu 22.9 N. Double cantilever beam
yang dibeberapa kasus memiliki tebal yang berbeda memberikan
hasil yang menunjukkan bahwa semakin tebal beam maka reaction
force yang dibutuhkan semakin besar.
============================================================
The development of composite materials is still on the rise.
One of them is the laminated composite material which consist of
lamina or multiple building-layers. The bond between the adjacent
lamina is often deformed. This phenomenon is commonly referred
to as delamination. Delamination in laminated composite
materials can be analyzed using numerical methods. In this
research, the finite element-based software, ANSYS
Mechanical/APDL, is used. The study assessed the delamination
process using double cantilever beam with displacement as a form
of load. The study used different variables including changing the
fiber orientation, the location of the initial crack, and the initial
crack length on double cantilever beam. The results show that the
double cantilever beam which had an initial crack length of 30 mm
and initial fiber direction of 0o has the highest reaction Force,
116.68, for the same beam size. Double cantilever beam with an
initial crack length of 55 mm and fiber direction 90° require the
smallest reaction Force, 22.9 N. This research also conclude that
the thickness of a double cantilever beam influences its reaction
force. The thicker the beam, the reaction force required will be
greater.
