  • Publication number: 20210059869
    Abstract: An absorbent article (1) of the present invention includes a leg cuff (24). The leg cuff (24) has leg elastic members (25). The leg cuff (24) can be divided, by an imaginary line (IL) passing through the center (ct) between an outermost leg elastic member (25s) that is located farthest outward and an innermost leg elastic member (25i) that is located farthest inward, into a leg cuff first region (ST) that extends from the imaginary line (IL) up to and including the outermost leg elastic member (25s) and a leg cuff second region (IT) that extends from the imaginary line (IL) up to and including the innermost leg elastic member (25i). When the elongation amount of the leg cuff first region (ST) and the leg cuff second region (IT) in a natural state is defined as 0, and the elongation amount thereof in a maximally stretched state is defined as 100, the stress in the leg cuff first region (ST) is greater than the stress in the leg cuff second region (IT) when the elongation amount is 5.

  • Publication number: 20200289340
    Abstract: A leak-proof cuff (28) is divided into a lower region (40) and a upper region (41). The upper region (41) includes a first region (41A) located at the side of a free edge (28B) relative to the center in the width direction (Y) and a second region (41B) located at the side of a folding line (42). In each of the first region (41A) and the second region (41B), at least one elastic member (29) extending along the longitudinal direction (X) is provided in a stretched state. In a case where the elongation of the upper region (41) in a natural state is 0, and the elongation in a maximum stretched state is 100, the stress ?1 of the first region (41A) is larger than the stress ?2 of the second region (41B) at an elongation of 5, and the stress ?2 of the second region (41B) is larger than the stress ?1 of the first region (41A) at an elongation of 100.

  • Publication number: 20150161295
    Abstract: A CAE analysis method is provided in which a computer is caused to perform modeling in which: a model formed by solid elements is applied for each of the plurality of members, based on given data representing a region to be analyzed of the plurality of members; a model formed by a shell element is applied for each weld joint formed between two members of the plurality of members, based on given data representing a region to be analyzed of the weld joints; and the shell element applied as the model for each weld joint is arranged inside a dihedral between welded surfaces of the two members, and is coupled to the solid elements applied as the model for each of the two members through internode connection such that each solid elements applied for the two members is coupled via rigid elements or beam elements to the shell element respectively.
