4.12 Orthotropic Surfaces and Membranes Dlubal Software

Orthotropic properties can be set for plane and quadrangle surfaces. You can define orthotropic properties via material (material orthotropy with invariable geometry), geometry (irregular shape of surface with isotropic material), or as a combination of both. The general stiffness matrix of an orthotropic surface in RFEM is as follows.Aluminum and Aluminum Alloys - NIST Aluminum sheet can be stamped, drawn, spun, or roll formed. The metal also may be hammered or forged. Aluminum wire, drawn from rolled rod, may be stranded into cable of any desired size and type.
