nThe stick-figure illustrations might lead some readers to think you are talking about beam elements. Beam elements do not have singularities. Solid elements most easily reveal the presence of a singularity.nThe basic reason for a singularity is that the theoretical stress is infinite. That happens when a force is applied to a point on solid geometry meshed with solid elements. Stress is Force/Area. The area of a point is zero, therefore stress is infinite. n
