Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. [1] Systematic selection of the best material for a given application begins with properties and costs of
In general, the yield strength of a material is an adequate indicator of the material's mechanical strength. Considered in tandem with the fact that the yield strength is the parameter that predicts plastic deformation in the material, one can make informed decisions on how to increase the strength of a material depending on its microstructural ...
Lumber’s price drop has been particularly dramatic in just the last 90 days in the futures market, with contract prices for July falling 28% to $466 per thousand board feet (futures prices are ...
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
Wood is relatively light in weight, because its specific weight is less than 500 kg/m 3, this is an advantage, when compared against 2,000–2,500 kg/m 3 for reinforced concrete or 7,800 kg/m 3 for steel. [citation needed] Wood is strong, because the efficiency of wood for structural purposes has qualities that are similar to steel. [citation ...
Wood physics, which constitutes an essential component of the field of wood science, building upon discoveries in wood chemistry, wood anatomy (xylem), and biology, as well as principles from classical physics, mechanics, and materials strength. [14]
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
Strength and stiffness - Glulam has a higher strength to weight ratio compared to both concrete and steel. Glulam also reduces the impact defects in the wood have on the strength of the member making it stronger than sawn lumber as well. [13] Glulam has also been proven to have a higher resistance to lateral-torsional buckling than steel. [14]
