| Abstract: | The basic unit of hull structure in waves is unstiffened plates. Therefore, precise assessment of ultimate strength of unstiffened plates is very important for ensuring the safety of ship structures. Calculation method of ultimate strength of unstiffened plates considering shear effect based on elastoplastic theory is presented; The influence of various parameters on the ultimate strength of unstiffened plates is studied; Compound and separate analysis method of shear stress and other stress effect are compared and feasibility and high efficiency of the separate analysis method are verified; Comparative study of this paper method with empirical formula and ABS rules is conducted. |
