Theoretical research & numerical simulation on the effect of urea-reactor layer plate gap on stress distribution

This paper takes diameter 1400 mm urea reactor as analysis targets, the study considered laminates space multilayered vessel stress field distribution, in the theoretical analysis on the basis of a large commercial software ANSYS based on the finite element numerical simulation validation, full consideration Clearance of laminates, It proves that formula of P.G. Pimshtein More suited to multi-layer containers stress field than formula of Lame. it provides a theoretical basis to such containers for the actual pilot fatigue analysis.
