This paper proposes a new expression for determining the reduction factor (FAR) of cracked square hollow section (SHS) K-joints.
Very detailed non-linear finite element analyses using 3-D mofels of compact tension C(T) fracture specimens with center cracked, square groove welds provide the evolution of crack growth with cyclic stress intensity factor which is required for the estimation of the closure loads.
For both cracked square and rectangular plate models, the influence of the boundary conditions, the crack orientation angle, crack length, and location of the point load is demonstrated.
The chapter proposes an approach to predict the ultimate strength of cracked square hollow section (SHS) tubular (T) joints.
This paper describes the usage of finite element (FE) analyses results to validate the standard BS7910 assessment procedure for the safe design of cracked square hollow section (SHS) T-, Y- and K-joints.
