Measurement Method for Elastic Modulus of Model Ice

摘要

The present invention relates to a method of measuring an elastic modulus of model ice by applying circular microstress. The purpose of the present invention is to provide a method which assumes a model ice plate formed in an icy water tank as an infinite plate to apply circular microstress to the infinite plate and measure micro displacement at the center of the circular shape to finally calculate the elastic modulus of model ice from the measured micro displacement. Provided is a method of measuring an elastic modulus of model ice by applying circular microstress which includes generating microstress by mounting a weight on a loading jig; applying the microstress to the model ice by the loading jig coming in contact with an upper surface of the model ice and applying equal microstress around the center of a linear variable differential transformer measurement unit; measuring the micro displacement of the model ice by the linear variable differential transformer measurement unit coming in contact with the upper surface of the model ice; and calculating the elastic modulus from a micro displacement signal of the linear variable differential transformer by a control unit.
