WebApr 11, 2024 · It is noted that the stress and strain concentrations occur at the edges of the plates bonded to the rubber; this is a well-known issue to designers of rubber components, and is mitigated by introducing filets in these regions. The detailing of such designs can be guided by FEA, as discussed by Gough & Muhr (2005). 3.3. WebThe observed stress can begin to grow at an increasing rate! This is referred to as a singularity. Singularities may have a number of causes, including: Point loads (loads applied over an infinitesimally small surface …
WebNov 23, 2010 · Stress Singularity All components have finite radii at corners, however for small radii a common simplification is to ignore the radius and make the corner 'sharp'. This may not matter for an external corner, however a sharp re-entrant corner results in a stress singularity - refining the FEA mesh will give increasing (without limit!) stress ... WebAnswer (1 of 2): Contact modeling in FEA is quite tricky but with correct settings you can get very accurate stress ouput at the interface. These are the most important factors: * correct mesh density - you need very dense mesh around the contact region to get accurate stresses * careful selec...
