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
Converting force and displacement into a stress-strain curve makes the response easier to interpret across key mechanical properties. Researchers can use the curve to examine stiffness, strength, ductility, and failure behavior as related features of one test result, rather than considering an isolated force or extension value. This supports structured comparison among samples.
A controlled extension rate establishes consistent loading conditions for each specimen. Testing samples at different rates can make their force and displacement records difficult to compare because the test conditions are no longer equivalent. Maintaining the prescribed rate helps researchers attribute differences among biomaterials, tissue samples, and scaffolds to the samples rather than to inconsistent testing conditions.
Specimen standardization and secure gripping create a consistent configuration for stretching each sample. This consistency helps the instrument produce comparable force and displacement records across biomaterials, tissue samples, and engineered scaffolds. In bioengineering, reliable specimen handling is especially important when researchers assess whether a construct reproduces the mechanical behavior of native tissue.
Applied force and displacement are the primary recorded outputs, but their value comes from interpreting them together. Researchers use these measurements to generate a stress-strain curve and evaluate stiffness, strength, ductility, and failure behavior. The resulting mechanical profile supports comparisons among samples and helps determine whether a material or construct has suitable structural performance.
Researchers apply the method to compare the mechanical properties of biomaterials, tissue samples, and engineered scaffolds under a consistent stretching condition. The resulting stress-strain data can show how closely an engineered construct reproduces native tissue behavior. These comparisons help identify differences in performance and guide evaluation of construct suitability for bioengineering research.
Mechanical results can inform material selection, device design, and the development of regenerative medicine strategies. Measurements of stiffness, strength, ductility, and failure behavior help researchers assess structural integrity and compare candidate materials or constructs. In this way, the test connects quantitative mechanical characterization with decisions about how biomaterials and engineered scaffolds should be evaluated.
