Automating the analytical verification of limit and fatigue hull strength for bulkers and tankers based on standard IACS rules
The purpose of this paper is to develop an optimal approach to automation of analytical verification for limit and fatigue hull strength of bulkers and tankers based on standard IACS rules. The paper discusses mathematical simulation of wave loads (pressures and bending moments) applied to the FEM model of hull, as well as the analysis of the stresses in hull structures obtained through multi-variant calculations. Analytical verification of limit and fatigue strength is automated by the inhouse software written in ANSYS Parametric Design Language for NSYS Mechanical APDL.
