Purpose: The aim of this paper is to propose a fracture model for human ribs based on acoustic emission (AE) data. The accumulation of microcracking until a macroscopic crack is produced can be monitored by AE. The macrocrack propagation causes the loss of the structural integrity of the rib.

- A study analyzed the mechanical properties of ribs from 64 human subjects of varying ages, sexes, and BMI to understand how these factors impact rib strength and flexibility.
- The researchers performed uniaxial tensile tests on rib bone samples, measuring properties like yield stress, ultimate stress, and resilience, aiming to isolate mechanical characteristics from shape influences.
- Results indicated that age significantly affects rib properties, with older age linked to lower failure stress and ultimate strain, and higher BMI further reduces strain in older individuals.

April 2021
A large number of post mortem human subjects was used to investigate the relation between the micro-structure of rib cortical bone and the mechanical properties using Fractal Dimension. Uniaxial tensile tests were performed on coupons of rib cortical bone. Tensile strength, yield stress, Young's Modulus, maximum strain, and work to fracture were determined for each coupon.
