Tissue biomechanics is important for maintaining cell shape and function and for determining phenotype. This report demonstrates non-destructive mechanical protocols for characterizing elastic and viscoelastic properties of human soft tissues, which can be directly applied to tissue-engineered substrates to allow a close matching of engineered materials to native tissue.

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...

Tests of Hardened Concrete in Tension

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA In a previous laboratory focused on concrete in compression, we observed that concrete can withstand very large stresses under uniaxial compressive forces. However, the failures observed were not compressive failures but failures along shear planes where maximum tensile forces occur. Thus, it is important to understand the behavior of concrete in tension and particularly its maximum strength...

FAQs
The curve separates elastic deformation, plastic deformation, ultimate tensile strength, and rupture. Elastic deformation describes behavior before permanent change, whereas plastic deformation indicates that the specimen no longer returns fully to its original state. The ultimate tensile strength identifies the highest tensile stress reached, and rupture marks failure. Together, these regions describe both load-bearing capacity and failure behavior.
A controlled elongation rate establishes defined test conditions so that force and length changes can be interpreted consistently. Keeping this condition fixed allows researchers to compare specimens, materials, or formulations more fairly rather than confusing differences in measured response with differences caused by the testing procedure. This consistency is especially important when evaluating tissues, hydrogels, biomaterials, or scaffolds.
The method can reveal stiffness, deformation behavior, and the point at which a specimen fails, not only its maximum tensile strength. Examining the complete stress-strain response shows whether a material primarily exhibits elastic or plastic behavior before rupture. These measurements help connect a material’s composition and structure with its mechanical performance and durability.
Changes in composition or structure can produce different stress-strain responses, including altered stiffness, strength, deformation behavior, or failure characteristics. Testing provides a way to observe those differences under the same defined conditions. In bioengineering, this comparison helps determine how material design choices influence mechanical performance and whether a candidate is suitable for a particular biomedical application.
A typical workflow places the specimen in grips, elongates it at a controlled rate, and records the applied force together with the change in length. The resulting measurements are used to generate a stress-strain curve. Researchers then examine elastic and plastic deformation, ultimate tensile strength, and rupture to characterize the specimen’s mechanical response.
Uniaxial tensile testing can compare natural tissues, biomaterials, hydrogels, and tissue-engineered scaffolds. Applying the same general measurement framework to these material classes supports evaluation of strength, stiffness, and failure behavior under defined conditions. The results help researchers identify how candidate materials perform mechanically and guide decisions about their potential biomedical use.
Measured mechanical properties provide evidence for selecting materials and refining designs. Strength, stiffness, deformation behavior, durability, and rupture characteristics can be compared with the intended performance of a biomedical material or tissue-engineered scaffold. By linking these outcomes to composition and structure, researchers can judge suitability and identify design choices that improve mechanical performance.
