ABSTRACT Fiber-Reinforced Plastics (FRPs) are being increasingly used in the study aims to compare the structural strength of a GFRP catamaran boat by varying material properties and fiber orientations using static structural analysis in ANSYS. The Hashin failure criterion was used to compare...

... of the system in terms of ultimate strength has been proved by comparing the calculated minimum safety factors with the required values while the obtained minimum fatigue life of primary and secondary membranes has shown that the system has enough fatigue strength. The system's sloshing resistance has also been...

The calculation procedures are based on ice strength values which is proved to be the main parameter but it determination meet many obstacles. The paper presents the correlation between ice strength and dynamic...

... is analysed in this paper. Results of finite-element simulations are presented for the RTPs with different material characteristics. Strength and buckling analyses have been performed considering a non-linear behaviour of the material. The minimum allowable bend radii of RTPs are determined. The effects...

... uncertainties related to both applied loading and material strength and time dependent degradation mechanisms. By the consideration of corrosion as the main cause of resistance deterioration, a time-dependent reliability analysis method can be used to investigate the ultimate strength of mooring system under...

The knowledge of the strength equations in the codes is useful for determining resistance factors for code calibration...

... an interesting and challenging topic for ship designers. Ice resistance is dependent primarily on ice thickness and flexural strength, and the ship's operating speed. Ice resistance determines the engine power and drives the propulsion system design. This is a crucial and expensive component of an icebreaking...

... to those of EG/AD/S model ice. The relatively large size of the MOERI Ice Model Basin made it difficult to control the initial strength of model ice and it took a much longer time to achieve the target strength. In order to obtain lower strength and stiffness for the model ice, the amount of chemical...
