The creep curve thus starts with an initial slope o / . Some strain then occurs and so some of the stress is transferred from the dash-pot to the spring. The slope of the creep curve is now 2/ , where 2 is the stress in the dash-pot, with 2 ever-decreasing. dakota health and wellness

"WebbStress is the average force per unit area that a particle of a body exerts on an adjacent particle, across an imaginary surface that separates them. The formula for uniaxial normal stress is: where σ is the stress, F is the force and A is the surface area. In SI units, force is measured in newtons and area in square metres.
