摘要: The bending strength of the sea ice cover is crucial in design ice-going vessels. Therefore, a series situ four-point tests have been performed earlier, which are now utilized to present particle swarm optimization–based procedure identify material parameters needed for numerical simulations. resulting simulations found comply well with experimental results terms force, failure time, and displacement. it can be concluded that presented optimization-based parameter identification also used future if similar found.
