STRUCTURAL MEMBER DESIGN METHOD, STEEL SHEET MANUFACTURING METHOD, TAILORED BLANK MANUFACTURING METHOD, STRUCTURAL MEMBER MANUFACTURING METHOD, AND STRUCTURAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/013676
Kind Code:
A1
Abstract:
This structural member design method is for designing a structural member obtained by molding a tailored blank. Said method includes: a welding part setting step for executing collision analysis, by numerical simulation, on an analytical model for the structural member, and setting the position of a welding part such that a breakage index of a first region is not less than a prescribed value and the breakage index of all remaining regions other than the first region is less than the prescribed value; and a removal region setting step for setting, after the welding part setting step, a region including a portion of a welded end part corresponding to the first region as a removal region where an exposing part is to be formed.
