Strength 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 کاملStrength 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 کاملDetection of Fatigue Cracks and Torque Loss in Bolted Joints
Fatigue crack growth during the service life of aging aircraft is a critical issue and monitoring of such cracks in structural hotspots is the goal of this research. This paper presents a procedure for classification and detection of cracks generated in bolted joints which are used at numerous locations in aircraft structures. Single lap bolted joints were equipped with surface mounted piezoele...
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 ...
متن کاملBolted Connection Strength and Bolt Hole Size
This study investigated the effects of oversized bolt holes on the properties of bolted connections with steel side members. The intent of the study was to determine (1) how well the European Yield Model (EYM) predicts experimental results for connections with oversized bolt holes and (2) how the loaddeformation behavior of connections is affected by oversized and/or misdrilled holes. Variables...
