Document Type and Number:
Japanese Patent JP2020170000
Kind Code:
A
Abstract:
To improve estimation accuracy, when estimating a material parameter after deformation of a porous material by using a material parameter before deformation of the porous material.SOLUTION: A material parameter estimation device 5 includes a reception part 51 for receiving inputs of a porosity φ(1) before deformation of a porous material and a volume change rate P of the porous material following deformation, and an estimation part 52 for estimating a porosity φ(P) after deformation of the porous material.SELECTED DRAWING: Figure 3
