Physical properties of surgical suture materials: Stress-strain relationship, stress-relaxation and irreversible elongation.


The stress-strain relationship, the stress-relaxation and the irreversible elongation of different suture materials were investigated. It was found that the distensibility of the fibers varied greatly. Most fibers were found to be chiefly elastic but some fibers were elastic when a moderate load was applied and plastic when the load increased. Some fibers… (More)
