Usually when you hear the term “stiffness” in strength training you conjure up negative associations, for example tight muscles, poor posture, and restricted movement. Another type of stiffness can occur when you encounter something like this (see pic) but that kind of stiffness is not appropri...
aMaterial selection requires consideration of many factors. Generally, strength, stiffness, ductility, weight, corrosion resistance, machinability, workability, weldability, appearance, cost, and availability must all be evaluated. Relative to the study of strength of materials, the first three of these...
is stiffness when the direction and magnitude of the force are constant. With machine tools, the moving part is not moving on the table.Strictly speaking, the table is deformed by the weight of the moving part. While the actual impact is extremely small, in some cases the machining precision...
kPa is often used in favor of pounds per square inch (PSI). The pascal, kilopascal, and gigapascal (GPa) are used to express tensile strength, compressive strength,Young's modulus, and stiffness of materials.
Production process: The advanced nature and stability of the production process is also a key factor in determining product quality. Some brands may have more advanced production equipment and technology that can more precisely control the thickness and uniformity of the coating, thus ensuring product...
the pressure of gases, known as pneumatic pressure, or liquids, also calledhydraulicpressure. PSI is also used as a measure of tensile strength, defined asresistanceto pulling forces, and elastic modulus strength, defined as resistance to deformation, which controls the stiffness of materials. ...
Composite materials are engineered by fusing different materials, typically consisting of a matrix (a polymer, metal, or ceramic) and a reinforcement (such as fibers, particles, or flakes) that provides strength and stiffness. The interaction between these components results in composite materials with...
peak stress value. When pulled further, fracture occurs, and the stress value at that point is known as the tensile strength. Elastomers, shown in green, are a unique class of polymers with rubber-like elasticity that can return to their original shape unless extended to the point of ...

The chemical composition of a material is a significant driver of its performance. A few atoms of aluminum in a titanium alloy can drastically change stiffness and yield strength. Measuring the atomic composition of an alloy under development or in production with the appropriate type of spectrometer...
