DEFORMATION DEVELOPMENT MECHANISM ANALYSIS OF TUBULAR T-JOINTS UNDER IMPACT LOADING

摘要：

　　Tubular T-joint is the basic type of joints in tubular truss,and study ofT joints is also the foundation of research of other type of joints.This paper aimed to reveal the deformation development law of tubular T-joint during the curse of impact by using of FEA software ABAQUS.By analyzing impact force,displacement,strain history curves,the impact process can be divided into three steps:loading step,local buckling step,and global inflection step.The deformation of joint can be looked as the coupling of local buckling and global flexural deformation,and equal area method can distinguish between local and global displacement.
