Inventor: YAMADA TAKEHISA
IPC: G01N3/34
Filed: 2009-09-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and a device for accurately evaluating the fatigue strength of a casting material having internal defects.  <P>SOLUTION: An S-N diagram is produced in advance based on results of a fatigue test performed on a plurality of prepared test pieces of a casting material. Each of internal defects of the respective test piece is modeled as a semi-circular or circular crack and a specific crack length a<SB>0</SB>thereof is calculated. An estimated fatigue limit σ<SB>w</SB>of each test piece is calculated based on the radium a<SB>eq</SB>and the specific crack length a<SB>0</SB>of the semi-circular or circular crack by the formula (2) σ<SB>w</SB>=σ<SB>w0</SB>[a<SB>eq</SB>/(a<SB>eq</SB>+a<SB>0</SB>)]<SP>1/2</SP>. A stress amplitude σ<SB>a</SB>of the S-N diagram is divided by the estimated fatigue limit σ<SB>w</SB>to produce an S-N diagram in consideration of internal defects. In the formula, σ<SB>w0</SB>is a fatigue limit of a material with no defect.  <P>COPYRIGHT: (C)2011,JPO&INPIT
