Regenerated isotropic wood | National Science Review ...

 · This bottom-up process exceeds the limitations of the anisotropic and inconsistent mechanical properties of natural wood, making regenerated isotropic wood (RGI-wood) a strong competitor for engineering plastics. Mass production of large sized RGI-wood can be achieved, overcoming the rarity of large sized natural wood.

Plastic Lumber Possibilities

In some applications, these new products are now displacing traditional building materials. 2 Global demand for these plastic lumber products is rising, due in part to an increase in their possible construction applications. The difference is in the mix. Wood–plastic composites (WPCs) consist of fibers combined with some sort of polymer.

ANISOTROPIC MATERIALS

Anisotropic materials are materials whose properties are directionally dependent. Unlike isotropic materials that have material properties identical in all directions, anisotropic material’s properties such as Young’s Modulus, change with direction along the object. Common examples of anisotropic materials are wood and composites. Implications

Introduction to Composite Materials

Materials can be classified as either isotropic or anisotropic. Isotropic materials have the same material properties in all directions, and normal loads create only normal strains. By compari-son, anisotropic materials have different mate-rial properties in all directions at a point in the body. there are no material planes of symmetry,

Elastoplastic Materials

Creo Simulate uses isotropic hardening laws to define elastoplastic materials. Hardening laws are rules that describe the relationship between the flow stress and the effective strain for a material. For hardening materials, the yield surface evolves in space. The yield surface expands in all directions in proportion to the strain increment.

Polymers | Thermoplastics

These materials change viscosity when heated, but seldom are as easy flowing as semi-crystalline materials. They are isotropic in flow, shrinking uniformly in the direction of flow and transverse to flow. As a result, amorphous materials typically exhibit lower mold shrinkage and less tendency to warp than the semi-crystalline materials.

Elastoplastic material with isotropic damage | Semantic ...

The two damage parameters needed to describe isotropic damage are shown to define a damage domain and the evolution of damage is defined by a path within that domain. Physical limitations on the path to full damage are developed. A thermodynamically consistent set of constitutive equations with which the damage path can be evaluated is developed for a specific material.
