Experimental investigation of single-lap bolted and bolted/bonded (hybrid) joints of polymeric plates

3-D Experimental and FEA Investigations of Thick Single-lap Bolted Joints

Stresses in single-lap bolted joints of thick plates are complex and difficult to analyze. The few previous studies of stress through the thickness of bolted joints have been limited to finite element simulations and have been implemented only for the joining of relatively thin plates. Experimental and numerical analyses were conducted to analyze the stress distribution inside thick bolted plat...

Investigation 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 ...

Hybrid Modelling of Multilayer Perceptron Ensembles for Predicting the Response of Bolted Lap Joints

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...

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...
