Question

4.WHAT IS CRITICAL PLANE OF
NECK? *​

Answer 1

Answer:

Critical plane analysis refers to the analysis of stresses or strains as they are experienced by a particular plane in a material, as well as the identification of which plane is likely to experience the most extreme damage. Critical plane analysis is widely used in engineering to account for the effects of cyclic, multiaxial load histories on the fatigue life of materials and structures.When a structure is under cyclic multiaxial loading, it is necessary to use multiaxial fatigue criteria that account for the multiaxial loading. If the cyclic multiaxial loading is nonproportional it is mandatory to use a proper multiaxial fatigue criteria. The multiaxial criteria based on the Critical Plane Method are the most effective criteria.

For the plane stress case, the orientation of the plane may be specified by an angle in the plane, and the stresses and strains acting on this plane may be computed via Mohr's circle. For the general 3D case, the orientation may be specified via a unit normal vector of the plane, and the associated stresses strains may be computed via a tensor coordinate transformation law.

Answer 2

The critical plane of the neck is the plane by which the stress and the strain of the neck is applied.

Explanation:

• the critical plane refers to the point where there is equal distribution of stress from all parts above the neck. for the neck it is the vertebrate through which the force and the stress is transmitted from the upper part of the neck and the brain to the rest of the body.

• As a result of this the vertebra is of very important factor for maintaining the the equilibrium of the forces with respect to the neck of the body.
