A thermo-mechanical analytical model and a corresponding macroscopic bonded joint finite element is presented for the analysis of orthotropic double lap joints subjected to combined thermal-mechanical loads. The analytical solution offers an improvement in accuracy over its predecessor, at the cost of increased solution complexity. However, to facilitate the use of this solution, it has been in...

Over the past few decades, there has been a considerable interest in the use of distributed optical fibre sensors (DOFS) for structural health monitoring of composite structures. In aerospace-related work, health monitoring of the adhesive joints of composites has become more significant, as they can suffer from cracking and delamination, which can have a significant impact on the integrity of ...

The significant features of the GFRP angle make it one modern construction members for present lattice-type Transmission Line Towers (TLT) made out mild steel. structural with gusset plate connections net-crushing strength are investigated in this study, an emphasis on to transmission line towers. Forty-two specimens single-lap, butt joints bolted considered study. and edge distance have differ...

A single lap joint is one of the most popular types adhesive joints. This very easy to apply and gives satisfactory results. However, there an extensive shear stress distribution at both ends in a shallow middle. In this research, performance test bi-adhesive with different widths was carried out. We modelled 2D FEM consisting adherent aluminum, two adhesives DP490 ESP110 then performed static ...

This paper is concerned with modelling damage and fracture in woven fabric CFRP single-lap bolted joints that fail by net-tension. The approach is based on the assumption that damage (matrix cracking, delamination and fibre tow fracture) initiates and propagates from the hole in a self-similar fashion. A traction-separation law (based on physically meaningful material parameters) is implemented...

Abstract In this study, the joint strengths of single-lap bolted and bolted/bonded (hybrid) joints formed by using four different engineering plastics were experimentally investigated. High-density polyethylene (HDPE), ultra-high molecular weight polyethylene, Delrin (POM), Teflon used as plate materials in connections. Standard M6 bolts bolt The specimens prepared single bolted, double bolted/...

Tujuan penelitian ini adalah untuk mengetahui Pengaruh Variasi Sambungan Las Listrik Terhadap Sifat Mekanik Pelat Stainless Steel 304L. Kegiatan dilakukan di Laboratorium Teknik Mesin Politeknik Negeri Manado. Pembentukan specimen uji tarik disesuaikan standar ASTM-E8. Penelitian dapat disimpulkan bahwa pemilihan diameter elektroda dan arus las sangat mempengaruhi kekuatan las. Tegangan maksimu...
