Abstract

The randomized method of Sign-Perturbed Sums (SPS) is applied within the framework of the incubation time approach to evaluate the dynamic strength of ice. The experimental data of [Carney et al., 2006; Wu and Prakash, 2015; Saletti et al., 2019] is analysed in order to estimate strength parameters of ice and describe the observed strain-rate sensitivity curves. The independence of incubation time value on the ice temperature is established in contrast with the significant dependency of the critical stress parameter. The obtained confidence interval of the spalled ice is in good correspondence with the scatter observed experimentally.

确定冰动强度的随机方法

在孵育时间法的框架内，应用随机符号摄动和法(SPS)来评估冰的动强度。实验数据[Carney et al.， 2006;Wu and Prakash, 2015;分析Saletti et al.， 2019]，以估计冰的强度参数并描述观测到的应变率敏感性曲线。与临界应力参数的显著依赖性相比，建立了孵育时间值与冰温的独立性。得到的散裂冰的置信区间与实验观测到的散裂吻合较好。
