Q: If a material has identical elastic properties in all directions, it is said to be
  • A. elastic
  • B. isotropic
  • C. homogeneous
  • D. orthotropic
Correct Answer: Option B - Isotropic– If its physical properties are identical in all directions (independent of orientation) it is called isotropic. An isotropic material has two independent elastic constants. Elastic– If the material recovers it original shape after the load is removed it is called elastic.
B. Isotropic– If its physical properties are identical in all directions (independent of orientation) it is called isotropic. An isotropic material has two independent elastic constants. Elastic– If the material recovers it original shape after the load is removed it is called elastic.
