Equivalent stiffness of clamped plates should be prescribed not only to evaluate the strength of bolted joints by the scheme of “joint diagram” but also to make structural analyses for practical structures with many bolted joints. We estimated the axial stiffness and bending stiffness of clamped plates by using Finite Element (FE) analyses while taking the contact condition on bearing surfaces ...

Due to constantly increasing traffic loads and ageing infrastructure, innovative materials for implementation in renovation new bridge construction projects are gaining attention. One such innovation is hybrid structures consisting of Glass Fibre-Reinforced Polymer (GFRP) composite decks connected a steel girder(s) superstructure. By combining the stiffness provided by members with superior fat...

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...

The quasistatic failure of composite-aluminium bolted joints is investigated experimentally using the stereo Digital Image Correlation (DIC) technique. Single-shear, two-bolt lap made carbon fibre reinforced polymer (CFRP) laminates and aluminium plates are subjected to tensile load while being monitored stereo-DIC. measured displacements processed by removing outliers Grubbs test reducing nois...

A method for detection and classiication of defects originating from rivet holes in a riveted lap-joint using eddy current (EC) inspection is presented in this paper. The EC-signals were acquired from a number of lap-joints using a tailor-made deep penetrating probe, and a digital single frequency EC-instrument. A number of rivets in the lap-joints had defects located in the second layer of the...

In this paper, the lap splice length and the long-term (fatigue) performance of lap-spliced carbon FRP laminates were investigated. Lap-spliced CFRP coupon specimens were fabricated with a splice length of 12.7, 25.4, 38.1, 50.8, 76.2, and 101.6 mm. To eliminate the bending on the lap splice joint, a symmetric specimen configuration was adopted. The width of the specimens was 38.1 mm. These spe...
