Hello!(adsbygoogle = window.adsbygoogle || []).push({});

I've found in my FE Analyses (For an 'L' shaped model) that for each value of Poisson's Ratio there exists a certain substanded angle above which the elastic solution has no stress singularity. Can somebody tell me what really a stress singularity means mathematically? and that why does it disappear above/below certain angles. I would also appreciate a detailed mathematical treatment of this problem.

Thanks,

Xishan
