Which of the following is NOT a mechanical property of biomaterials?

Thermal conductivity is not considered a mechanical property of biomaterials. Mechanical properties typically pertain to how materials respond to applied forces or loads, and include characteristics such as tensile strength, compressive strength, and fatigue resistance. These properties describe materials' abilities to withstand tension, compression, and cyclical loading, respectively, which are critical when evaluating their performance in biomedical applications.

Thermal conductivity, on the other hand, refers to a material’s ability to conduct heat, which falls under the category of thermal properties rather than mechanical properties. Understanding the distinction between mechanical and thermal properties is essential in the field of biomedical engineering, as it informs the selection and evaluation of materials for specific applications in medical devices and implants.
