Snap fit
Although the snap-fit approach is the simplest and most economical way to assemble parts, the strain (ε) of the snap-fit part should be kept below 6% for general grade and composite reinforced grade and 2 to 2.5% or less after assembly. Please design to eliminate any significant distortion.
Reference the corner R (stress concentration) page for values of R.
