概括

在经过内牙治疗的牙中,围牙病变对整体压力的影响很小,但会显著增加局部压力和变形. 较大的病变会对大中央切口的生物力学稳定性产生负面影响.

Stress Concentrations01:24

Stress Concentrations

Stress concentration is when stress intensifies near discontinuities such as holes or abrupt cross-sectional changes in a structural member. This localized stress can often surpass the average stress within the member. The stress distribution in flat bars, either with a circular hole or varying widths connected by fillets, can be determined experimentally using a photoelastic method. The results are based on ratios of geometric parameters like the ratio of the hole's radius to the smaller...
