And also the number of spot-welds (discrete variable) was selected as one of the design variables in optimization.
The results show that the SEA for (n < 10) does not meet the constraint of (SEA [greater than or equal to] 9); therefore, the minimum number of spot-welds is 10.
This is done by enumerating the number of spot-welds n and optimizing the design variables for each n.
In this paper, crashworthiness of spot-welded columns was studied when no spot-weld failure occurred.
that the SEA for (n < 10) does not meet the constraint of (SEA = 6); therefore, the minimum number of spot-welds is 10.
Dynamic experiments lead to the observation that axial shortening was significantly larger in those specimens that had some ruptured spot-welds although load (mass and initial speed) was the same in all the cases.
Now, let's investigate the influence of impaired spot-welds on the deformation of the specimen.
092 m, failure of the spot-welds in those positions where a wave forms at the initial moment causes the energy absorbed by the specimen to reduce by 15%;
