The incident wave heights for breakup of ice flee with different lengths, and the influence of rigidity on reflection and transmission coefficients are discussed. The experimental results show that the ratio of the ice noe length, L-i, to the wavelength, L, is one of the significant factor affecting the minimum wave height to cause fracture of ice flee, and another key factor is the ratio of the ice flee thickness, h(i) and L-i.展开更多
