If structural analysis reveals stress concentration points, ribs can be added as a countermeasure to
The ribs are added as a countermeasure to try to disperse the stress concentration.
However, the addition of ribs does not necessarily have the effect of dispersing stresses.
For example, when triangular ribs are added to stress concentrations in an L-shaped model to disperse the stresses
The stresses are concentrated at the boundaries where the ribs have been added and the stress peak values are higher than before the measures were taken. This can be attributed to the inappropriate setting of the added triangular ribs.
This is the result of reviewing the size of the triangular ribs. The peak value of the maximum stress could be reduced.
The addition of inappropriate geometry can conversely be a factor in stress concentration.
However, they are difficult to predict due to the restraint conditions and product geometry.
When designing a product, it is difficult to improve design efficiency unless structural analysis using CAE is carried out at the same time.
