Abstract
DREA conducted a joint structural testing project with the U.S. Interagency Ship Structures Committee (SSC) at C-FER (Centre for Engineering Research Inc., Edmonton) earlier this year. Twelve stiffened plates, seven without damage and five with damage, having dimensions approximately equal to a typical stiffened panel at the strength deck of the Canadian Patrol Frigate (CPF) were tested. One of the objectives of this project was to conduct a computer simulation of the test procedure with the non-linear finite element method. It was hoped that after a successful simulation, panels with other dimensions and parameters could be studied numerically. As the scientific authority of this project, the author planned the test procedure, conducted the numerical prediction of the collapse load of the specimens, and performed the computer simulation of the test procedure. Because of the complexity of the computer simulation and completely different behaviour between damaged and undamaged specimens, this memorandum only summarises the finite element results on specimens without damage and their relation with the test observations. Seven specimens, which failed either in tripping or in combined plate and flexural buckling modes under combined lateral and axial loads, were modelled. Some interesting buckling phenomena were discovered and are discussed.
