Why are sharp contours stress concentrators?

    intuitively it makes sense but what is the scientific explanation

    Stress concentrations are due to abrupt geometrical changes that cause the flow of stress to concentrate (
    visualize stress contours tightly packed at the discontinuity). From a theoretical scientific point of view, these stress concentration factors can be calculated using elasticity theory and plate analysis and a lot of messy partial differential equations. Or by computer finite element approach (caution, this sometimes leads to infinities).
