Abstract In order to quantitatively study the relationship between shear strength and fractal dimension,and multifractal spectrum of TA2/Q235 explosive welded composite plate under service condition,and to identify the best fractal characterization method for TA2/Q235 composite plates,the service processes were simulated by heat treatment,shear experiments of the samples after service were carried out,and the fractal theory was introduced to characterize the shear fracture interface. The purpose of the above study is to establish the relation among shear strength,fractal dimension,and multiple fractal spectrums. The results show that after 200,400 and 600 ℃ service,the shear strength of the sample is negatively correlated with the width of the fracture multiple fractal spectrum. Combining with the analysis of the influence of residual stress elimination and recrystallization growth on shear fracture morphology of TA2/Q235 explosive composite plate,and comparing with fractal dimension,the multifractal spectrum can more accurately describe the mechanics′ information of fracture interface.
