Strength Prediction of Double-Lap Woven CFRP Bolted Joint Incorporating Material Softening
نویسندگان
چکیده
Strength prediction is discussed using a traction-separation damage model incorporating material softening for bolted joint that fails in bearing mode. The modelliug approach in the bolted double-lap joint of current work is a simplistic approach to predict the strength of bearing failures. This is clearly shown in bearing failure which occurred experimentally at higher W/d ratios. A simple method for degrading material properties in the region of bearing failure was investigated and, Erom a preliminary study, was found to be promising. This approach is easily-implemented, and has been shown to be applicable to woven fabric composite materials in double-lap bolted joint.

Strength Prediction in CFRP Woven Laminate Bolted Double-Lap Joints under Quasi-static Loading using XFEM
The current paper is concerned with modelling damage and fracture in woven fabric composite double-lap bolted joints that fail by net-tension. A 3-D finite element model is used, which incorporates bolt clamp-up, to model a range of CFRP bolted joints, which were also tested experimentally. The effects of laminate lay-up, joint geometry, hole size and bolt clamp-up torque were considered. An Ex...
متن کاملStrength Prediction in CFRP Woven Laminate Bolted Single-Lap Joints under Quasi-static Loading using XFEM
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...
متن کاملFinite Element - Based Strength Prediction for Notched and Mechanically Fastened Woven Fabric Composites
A literature review has been carried out relating to the damage and fracture behaviour of composite laminates based on woven fabric reinforcement containing a stress raiser in the form of either a circular hole or of a mechanically fastened joint – the tensile failure modes in these two types of problem are very similar. Closed form and finite element based approaches that enable the stress dis...

In this study, analytical models considering different material and geometry for both single and double-lap bolted joints were reviewed for better understand how to select the proper model for a particular application. The survey indicades that the analytic models selected for the adhesively single or double bolted lap joints, as well as T, scarf, and stepped joints, with linear material pr...
متن کاملInvestigation on the Effect of Tigthening Torque on the Stress Distribution in Double Lap Simple Bolted and Hybrid (Bolted -Bonded) Joints
In this research, the effects of torque tightening on the stress distribution in double lap simple bolted and hybrid (bolted-bonded) joints have been investigated numerically. In order to determine the bolt clamping force value due to tightening torque in simple bolted and hybrid joints, which is necessary in numerical simulation, an experimental approach has been proposed. To do so, two kinds ...
