Assessing Cyclic Response of the Wind Mill Using Hypoplastic Clay Model

Hypoplastic constitute law is best choice to predict the non linear behavior of the soil. Hypoplastic constitutive laws are used to describe the deformation behavior of the granular soil and clay at a given strain rates. In constitutive law the soil deformation behavior is explained in term of soil stress and strain rate in which stress and strain rates are regarded as function of time[1]. In case of soil the stress tensor is not only a function of strain as in case of elasto plastic material but instead complete deformation history is required to predict the  behavior of the soil [2]. In this blog i am going to explain the installation as well as response of the windmill under cyclic load by taking an example of reference study by Hong et al [3].
