我们提出了一个概率策略,高档的材料空间变异性从细到粗尺度。为了在数值框架中实现这一想法,我们认为粗尺度是随机的,即,其材料特性被认为是不确定的,并且被建模为随机变量/场。数值算例验证了该方法的有效性.(© 2016 Wiley‐VCH Verlag GmbH & Co. KGaA,魏因海姆)
We propose a probabilistic strategy to upscale the material spatial variability from fine to coarse scale. To implement this idea in a numerical framework, we consider the coarse‐scale as stochastic, i. e. its material properties are considered uncertain and modeled as random variables/fields. Numerical examples are shown to demonstrate the applicability of proposed approach. (© 2016 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
