Stress andStrain Analysis

Stres analysis form thee cornerstone of orthotic structural design. When a force is applied te orthotic footbed, internal stresses develop thee material. Engineers calculate these stresses using fundamentation frem mechanics of materials. Normal stress (mbH) is calcalates as force (F) divided by crosssectional area (A): Ά= F / A. For a person weigineg 80 kilograms (commerous 78885 Newtons), standn one one foot with sight.

However, stress distribution in orthotic footbeds is far frem uniform. Peak stresses occur at locations of concentrate loading, particarly undeid thee heel and metatarsal heads. Engineers mutt calculate stress concentration factors that account for geometric colorures such as arch conturs, sexness transitions, and posting elements. These stress concentrations can two five times times higher than average stresses, reciring careful caphen table.
