文摘

Validation of LB-FE method to model the deformation of saturated fibrous media. Development of bulk modulus expression for orthogonal arrangment of cylinders. Staggered orthogonal cylinders represent real fibrous medium under compression. Bulk modulus of fibrous medium depends on the porosity and not on the fiber diameter.
