Fatigue Behaviour of Fastening Joints of Sheet Materials and Finite Element Analysis

Abstract

Some fastening techniques such as self-piercing riveting, mechanical clinching, and structural adhesive bonding are efficient joining methods which are suitable for joining advanced lightweight sheet materials that are hard to weld. The recent literature relating to fatigue behavior of such fastening joints and finite element analysis is reviewed in this paper. The recent development in fatigue behavior analysis of the fastening joints is described with particular reference to some major factors that influence the fatigue behavior of the fastening joints: failure mechanism, environmental effects, and hybrid joining techniques. The main methods used in finite element analysis of fatigue behavior of the fastening joints of sheet materials are discussed and illustrated with brief case studies from the literature.

Influence of Tool Shape on Hole Clinching for Carbon Fiber-Reinforced Plastic and SPRC440

“…and are the punch diameter and neck thickness, respectively. For the given joint strength of 2.5 kN, multiple solutions to (2) are possible, as shown in Figure 7. The lower limit of was determined from the geometrical relationship in the control volume ( ) for hole clinching, as shown in Figure 5.…”

“…Increasing the size of a hole-clinched joint is an efficient way of increasing joint strength, because the fracture area is dependent on the punch diameter according to (2). However, the hoop stress increases with the increase in the punch diameter, which may split the bottom material of a holeclinched joint during spreading into die cavity, as shown in Figure 13.…”

“…Use of carbon fiber-reinforced plastic (CFRP) laminates has especially increased in the automotive industry owing to their low density and good mechanical properties [1][2][3]. However, the joining of dissimilar materials, such as CFRP laminates with other materials, is still one of the main issues that must be resolved for successful multimaterial design.…”

The Unsteady Numerical Simulation and Fluid-Structure Interaction Analysis of TLB600-700 Desulphurization Pump

“…The constant calculation of fluid calculation regions is defined with pressure inlet and mass flow outlet as boundary conditions. The calculation results are imported to ANSYS Workbench; in such way the fluid-structure interaction analysis could be obtained by loading the corresponding pressure into the impeller entity part [15,16].…”

An Analytical Model for Predicting the Stress Distributions within Single-Lap Adhesively Bonded Beams

“…The use of adhesively bonded joint, which uses metallic, composite, and ceramic materials, is of great interest to many industrial sectors including aerospace, automotive, marine, machine tools, package, and appliance industries. This widespread use of adhesive joints is due to ease of application, time and cost savings, high corrosion and fatigue resistance, crack retardance, and good damping characteristics [1][2][3].…”
