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.

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.

Non-destructive Tests for Concrete Strength

The rebound hammer test, also known as the Schmidt hammer test, is a non-destructive technique for evaluating the hardness of concrete and, indirectly, the strength of concrete. It operates on the principle that the rebound of a spring-driven mass from a concrete surface correlates to the surface's hardness. The device comprises a mass within a tubular housing, a spring mechanism, and a plunger that strikes the concrete. Upon release, the energy imparted to the mass by the spring causes it to...
FAQs
A stress–strain curve shows how a specimen responds as the applied pulling load increases. Its shape helps distinguish stiffness, elastic behavior, and the point at which failure occurs, rather than reducing performance to a single strength value. In bioengineering, this broader profile helps researchers compare how candidate materials behave under progressively increasing mechanical demands.
These properties describe different parts of the mechanical response. Tensile strength concerns the greatest load-related resistance before failure, stiffness reflects resistance to deformation, and elasticity describes recovery-related behavior within the material’s response. Failure behavior indicates how the specimen ultimately breaks or loses structural integrity. Considering all four prevents selection based on strength alone.
Controlled axial loading applies the pulling force along the specimen’s intended test direction, while grips hold the specimen so force and elongation can be recorded together. This arrangement supports generation of a meaningful stress–strain curve and helps relate the measured response to the material itself. It is especially important when comparing different biomaterials or scaffold designs.
A typical workflow places a prepared specimen between grips, applies a controlled axial load, and records the resulting force and elongation throughout the test. The collected measurements are then used to generate a stress–strain curve and identify strength, stiffness, elasticity, and failure characteristics. The same sequence can be applied to biomaterials, sutures, scaffolds, or engineered tissues.
Bioengineers use this testing when they need to assess whether a biomaterial, tissue scaffold, suture, or engineered tissue can meet expected structural demands. The resulting mechanical measurements support comparison among candidate materials and help identify designs with suitable resistance to deformation or failure. This makes the method relevant during development of biomedical products and engineered biological constructs.
Measured tensile properties provide evidence for material selection and device design by showing how a candidate performs under pulling forces. The same results can also support quality control, helping evaluate whether biomedical products maintain the intended structural performance. Comparing stress–strain behavior and failure characteristics with physiological demands can guide development of stronger and more reliable products.
