Stress

Question 1

A force applied to a material that tends to change that materials dimension

Answer 1

Stress

Question 2

The stress that tends to pull something apart. It is the stress component perperndicular to a given surface to the fault palne, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.

Answer 2

Tensional stress

Question 3

The stress that squeezes something. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.

Answer 3

Compressional Stress

Question 4

Stress vector acting across plane of zero shear stress

Answer 4

Principal stress

Question 5

acts perpendicular to a reference surface

Answer 5

Normal Stress (σn)

Question 6

Acts parallel to a reference surface

Answer 6

Shear Stress (τ)

Question 7

Principal Normal Stress Components

Answer 7

(σ1> σ2> σ3)

Question 8

The non-hydrostatic of stress, expressed as total stress with mean stress subtracted from the normal stress components.

Answer 8

Deviatoric Stress
