Concentrationstress leads to calcifying the valve leaflet near the point of calcification further seriously.
当瓣叶出现钙化时，钙化点及其周围产生应力集中，促进钙化的进一步加剧。

The fatigue life of different welding shapes between plates of unequal thickness in pressure vessel was investigated from the point of local stressconcentration at welding position.
从焊接部位局部应力集中的角度分析了不等厚板在不同焊接形式下的疲劳寿命。

At this point conversion, beam bear a greater vertical force, the bottom of beam appears large tensile stress easily. The conversion layer slab with upper wall appears stress concentration easily.
