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...

However, for slender steel structures both the ice crushing and bending failure may lead to ice induced vibration of the structure. Several theories have been proposed to predict these vibrations, but the physically details...
