PROBLEM TO BE SOLVED: To calculate a stress (stress distortion) in a specified arbitrary area specified by a user easily with high accuracy without recalculation by the algorithm of the finite element method.SOLUTION: After a calculation means 17 calculates stresses of a plurality of joints Y in an analysis object data D, a designated area AL designated by a user is arbitrarily set to the entire area of the analysis target data D, via input means 3, 4. In this state, a reference joint generation means 19 generates a plurality of reference joints P1-P4 on a contour line AL1 of the designated area AL. At this time, by the disposition of a reference joint P5 in the designated area AL to the vicinity of a joint to be analyzed, a calculation means 20 obtains the values of the reference joints P1-P4 based on the stress value of the peripheral joints Y adjacent to the plurality of reference joints P1-P4, and obtains the stress of the designated area AL to be analyzed by averaging the obtained values of the plurality of reference joints. Owing to this, the stress in the joint Y in the specified area AL can be obtained without recalculation of the algorithm of the finite element method. |
