固体与结构弹性模量的普适定律

Universal Law for the Elastic Moduli of Solids and Structures

S. J. Burns, Sean P. Burns

AI总结:

该研究将晶体剪切模量仅依赖比容的定律推广至所有弹性模量,提出弹性模量作为比容幂律的普适定律,并经多种材料实验验证。

摘要:

先前针对晶体材料剪切模量发现的一条定律被发展并推广至固体与结构中的所有弹性模量。此前研究表明,剪切模量仅取决于比容。如今,通过将弹性视为比容幂律,许多材料和结构的体积模量可被解析预测,并经实验证实具有无误的准确性。该定律得到了来自泡沫材料、Schneebeli二维石墨烯垫、超材料、全致密金属、陶瓷和矿物的实验证据支持。这一新的、广义的、普适的弹性模量定律始终适用于能承受剪切应力的材料,即固体;研究表明,所有弹性模量都仅直接取决于比容。

英文摘要:

A law previously found for shear moduli of crystalline materials is developed and extended to all elastic moduli in solids and structures. Shear moduli were previously shown to depend only on specific volume. The bulk moduli of many materials and structures are now predicted analytically and empirically shown with unerring accuracy by observing the elasticity as a specific volume power law. The law is supported by experimental evidence from: foams, Schneebeli 2-dimensional graphene mats, metamaterials, fully dense metals, ceramics and minerals. This new, generalized, universal, elastic moduli law always describes materials that support shear stresses i.e., solids; it is shown that all elastic moduli are directly dependent only on the specific volume.
