Resumo: | This paper is aimed at studying the behavior of the band of inferior glenohumeral ligament subjected to uniaxial traction. Twenty ligaments were distributed in two groups: Group I ( ligaments with bony origin and insertion) and Group II ( medial portion of the ligament). Uniaxial traction was applied to all tendons utilizing a traction machine develop in the Department of Physics of UFC. Hooke's Law was used for evaluation of ligament behavior during elastic phase and the Exponential stress-strain Law, for rigidity phase. All ligaments had the same behavior, presenting a phase of elasticity , followed by one of rigidity. After evaluation of the elastic phase , applying Hooke's Law, ligaments constants were 10.507 N/mm ( group I ) and 13.80 N/mm ( group II), suffering a straining of 2.83% and 2.84%,respectively, until the ligament became rigid. During rigidity phase, the constants were 511.56% N/mm (group I) and 156.84% N/mm (group II). It is concluded that the ligament submitted to traction suffers a small elongation until becoming rigid along with an important increase in force constants during rigidity phase. |

Hooke's Law was used for evaluation of ligament behavior during elastic phase and the Exponential stress-strain Law, for rigidity phase.
