Question

Unidirectional fiber- reinforced composites also exhibit _______ behavior.

(a) Isotropic

(b) Orthotropic

(c) Material

(d) Unidirection composite

The question was posed to me in examination.

I'm obligated to ask this question of Two Dimensional Problems topic in portion Two Dimensional Problems using Constant Strain Triangles of Finite Element Method

Answer 1

Right choice is (b) Orthotropic

To explain: Orthotropic materials have material properties that differ along three mutually orthogonal two fold axis of rotational symmetry. They are a subset of anisotropic materials, because their properties change when measured from different directions.
