Abstract

Material komposit polimer dengan serat alam telah banyak digunakan di berbagai bidang kehidupan. Beberapa serat alam seperti serat lenan, hemp, kelapa sawit, dan bambu yang dikombinasikan dengan matrik polimer digunakan untuk industri otomotif, komponen struktur bangunan, pengemasan, dan konstruksi. Dalam penelitian ini dianalisis pengaruh perlakuan alkali serat rumput payung (cyperus alternifolius) terhadap kekuatan tarik komposit dengan matrik epoxy. Pengujian kuat tarik komposit dilakukan dengan mengacu pada ASTM D638- 02a. Komposisi komposit serat rumput payung terdiri dari 80% serat dan 20% matrik epoxy. Serat diberikan perlakuaan alkalisasi (5% NaOH) dengan variasi lama perendaman 0 jam (tanpa perendaman), 1 jam, 2 jam, dan 3 jam. Dari data pengujian diperoleh hasil Nilai Prerata maksimum dan srerata maksimum, masing-masing sebesar 6690 N dan 73,52 N/mm2  terdapat pada spesimen dengan durasi perendaman 1 jam, sedangkan nilai Prerata minimum dan srerata minimum masing-masing sebesar 4385 N dan 56,22 N/mm2 terdapat pada spesimen tanpa perendaman.

Abstract

A gusset plate is a member of a bridge structure that is significantly subjected to cyclically varying loads. It may collapse after a certain number of cycles. However a single cycle may causes structural failure although the maximum stress (due to loading) is much less than the yield or the ultimate stress of the material. In a case of notched component under such conditions, high-intensity stress will occur at the zone of the notched component. Fracture mechanics is strongly recommended in a bridge design especially for joints. It will determine the moment at which fatigue cracks will occur and how far it has propagated. This study explores a fracture phenomenon of a steel gusset plate due to fatigue loading. Modeled as a double-edged notched plate, the failure stress is found to be less than the ultimate stress of the material. By assuming that crack closure exist, the results of this study provide a significant conclusion: under a constant failure stress the rate of fatigue growth increases as the crack propagates. Keywords: Fracture mechanics, fatigue loading, stress intensity, double-edge notched
