Static Stability Determination Of An Exhaust Stack Structure Using Finite Element Analysis / Kamarul Nizam Hassan ... [et al.]

The stability analysis of exhaust stack is generally governed by two physical factors, i.e. the intricacy of the stack shape and the height-to-diameter ratio and the nature of the the loadings it supports. In this study, an A516 Grade 70 steel cylindrical tubing exhaust stack subjected to its self-w...
