| Research Abstract |
The experiments were carried out using grass leaves in order to clarify the relationship between physical strength of plant materials and grazing behaviour of cattle and horse. In comparison of biting strength per bite by domestic animals with breaking strength of leaves, shearing force may play an important role in breaking plant materials. For a calculation of modulus of section, which seriously affect bending strength of grass leaves, the double triangle model and the double parabolic model were made and applied to a calculation of modulus of section.
