Abstract

This paper presents the simulation and experiment work on the prediction of stress analysis in asingle lap bolted joint under bending loads. A three-dimensional finite element model of a boltedjoint has been developed using MSC Patran and MSC Nastran FEM commercial package. In thesimulation, different methods in modelling the contact between the joint, which affects theefficiency of the models were detailed. Experimental work was then conducted to measure strainsand deformations of the specimens for validation of the developed numerical model. A four-pointbending load type of testing was used in both the simulation and experiment works. The resultsfrom both simulation and experiment were then compared and show good agreement. Severalfactors that potentially influenced the variation of the results were noted. Finally, critical areaswere identified and confirmed with the stress distribution results from simulation.
