Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut For over 4000 years, sutures have been used as a medical intervention. The earliest records indicate linen was the biomaterial of choice. Catgut, which is still in use today, was reportedly used to treat gladiators around 150 AD. Today, there are numerous materials being used for sutures. Sutures are classified by their composition (natural or...

Tensile Strength Considerations of Concrete

Considering the tensile strength of concrete involves recognizing that the theoretical strength of cement paste can be up to a thousand times higher than what is observed in practical applications. This significant discrepancy is largely attributed to the presence of microscopic cracks within the concrete. These cracks tend to amplify stress at their tips when a load is applied, a phenomenon explained by Griffith's theory of brittle fracture. The dimensions and shape of a concrete specimen also...

Relation Between Tensile Strength and Compressive Strength of Concrete

Concrete is a fundamental building material, and understanding its strengths is crucial for construction projects. The relationship between its tensile and compressive strengths is intricate, showing that while these strengths are related, they do not increase at the same rate. Tensile strength's growth is slower and is affected by various factors such as the methods used for testing, the size and shape of the specimen, the texture of the aggregate used, and the moisture content of the concrete.

In this video, we demonstrate suturing techniques — core suture and Q suture — to repair the foot flexor tendon in an ex vivo porcine model. Q sutures enhance the strength of the core suture in tendon repair and decrease gapping at the tendon repair site.
FAQs
A stress-strain relationship separates several mechanical features that a single force value cannot show. The slope-related response indicates stiffness, while the recoverable response reflects elasticity; the highest point identifies ultimate strength, and the final portion describes failure behavior. Together, these features show how a biological material responds as loading progresses toward structural damage.
Composition, organization, and damage can produce different tensile responses among biological materials. Comparing these factors helps explain why tissues or biomaterials differ in stiffness, elasticity, ultimate strength, and failure behavior. This comparison connects structural features with mechanical performance, allowing researchers to evaluate how changes in tissue condition or material design may affect function.
Failure behavior shows how a specimen loses structural integrity after it has been loaded toward its limit. Rather than focusing only on the maximum force, researchers can examine the broader stress-strain response to identify how stiffness, elasticity, and ultimate strength relate to breakdown. This provides a more complete picture of material performance under pulling forces.
During the test, researchers stretch a specimen while recording the applied force and its deformation. They then use these measurements to construct a stress-strain relationship, which supports evaluation of stiffness, elasticity, ultimate strength, and failure behavior. The resulting profile provides a consistent way to compare structural performance among tissues, scaffolds, or prosthetic materials.
Tensile strength measurements are especially relevant to collagen-rich tissues, including tendons, ligaments, skin, and blood vessels. Testing these materials helps characterize how their structural integrity responds to pulling forces. The same approach also supports comparison with engineered scaffolds and prosthetic materials, linking biological tissue mechanics with the performance requirements of designed replacements.
By comparing stress-strain responses, researchers can assess whether engineered scaffolds or prosthetic materials provide mechanical characteristics relevant to biological tissues. These measurements also help examine how composition, organization, and damage relate to function. In tissue repair research, the comparisons can inform evaluation of structural performance and guide efforts to match material behavior with biological requirements.
