PCBs are typically made from FR-4/G-10--a nonmetallic insulating material that is orthotropic and exhibits material properties very different from those of metals.
Today's polymer materials have been used on concrete, concrete-filled steel grid, steel orthotropic, fiberglass reinforced plastics, and wooden bridge decks.
Resulting stress-strain data allow the determination of mechanical properties of bundle to combine with the geometry, boundary conditions, constraints and periodicity of rubber-matrix composite for homogenization, in the end, orthotropic elasticity constants are destined for computer modeling of the whole rubber product.
The Uni-body deck is supported with orthotropic steel channel beams that minimize the potential for deck "dishing," a common problem with shipping dock floor scales.
The orthotropic character of FRP entails up to nine moduluses of elasticity, and FRP equipment is typically designed on the basis of allowable strain rather than stress.
In sororia, initial growth resulted in orthotropic rosette shoots with short internodes (Fig.
and in a subsequent interview with PLASTICS TECHNOLOGY, Koster says that advanced designs such as the Porsche 959 and BMW Z-1 roadster demonstrate a trend toward a "continuous structure concept" for cars, in which horizontal panels such as doors and hoods become orthotropic load-bearing members without B-supports (similar to aircraft and bank-vault doors).
The new superstructures are designed as bar arch bridges with orthotropic carriageway slabs according to the langer~s beam system.
Unlike common isotropic material, 5 independent parameters are needed to describe stiffness performance of orthotropic composite materials, such as carbon fiber composites and glass fiber composites.
Numerical methods based on boundary integral equations are powerful tools in many areas of engineering and science including theory of orthotropic plates [1], anisotropic plates [2] with cracks and thin rigid inclusions.
