Analysis of Hull Girder Ultimate Strength and Residual Strength Based on IACS CSR-H

Table 3

Boundary conditions used in NFEM.

Position	Displacement constraint			Rotation constraint
	Fore end plane	Coupling	Coupling	Coupling	-	Coupling	-
Aft end plane	Coupling	Coupling	Coupling	-	Coupling	-
Independent point A	Fixed	Fixed	Fixed	Fixed	Fixed	-
Independent point B	-	Fixed	Fixed	-	Fixed	-

Note: independent point A and point B are defined in FE model, of which position can be located at the intersection point of neutral axis in cross section.
