Stress is the amount of force per unit area (N/mm2; lb/ft2)
Strain is the unitless change in length resulting from the application of a force (movement in unit length / original unit length)
Young's Modulus relates the two (stress / strain)
a stress strain curve and a load displacement curve is pretty much the same thing, given the data is from the same specimen. its just the stress (force/area) is divided by a constant area and the strain (change in length/original length) is divided by a constant original length. therefore your curve would pretty much look the same as dividing by a constant will not change your graph. hope this explains your question
Stress is the tension/compression force per unit area.Strain is the ratio of change of length to the original length, due to applied force.Tension is the applied force which tends to elongate the body.
stress= force/C.S.A. so fracture stress = force at fracture / Cross.Sectional.Area.
depresion etc.
fatigue
stress strain curve details
Wherever there is stress there is strain. In the example you noted, if heated bar expands freely without one end constained it changes its strain without stress; that strain is called eigenstrain. If the same bar is held rigidly then the eigenstrain resisted and you get stress and strain. So stress cannot exist without strain; but strain can exist without stress if it is eigenstrain.
stress is load per unit area; when an object is loaded it is under stress and strain and it stretches (strains) until it breaks at its ultimate strength. Stress i srelated to strain in the elastic region by Hooke's law: stress = elastic modulus times strain where modulus is a property of the material and strain is deflection over length
stress is directly proportional to strain up to the proportional limit. Their ratio is young's modulus.
The strain gage indicates strain, and the stress is from Hooke's law; stress = modulus times strain so you need to know the modulus of elasticity
The secant modulus is the total stress or strain on an object as described by a stress-strain graph. The tangent modulus is the marginal strain.
When you have stress you also have strain - stress cannot exist without strain, so they come at the same time You can have strain without stress - like expanding something under temperature in a free state. If the state is not free, then you have stress occurring at the same time.
is defined as ratio of uniform stress to volume strain
difference between Strain-stress diagram of copper and steel?
the leading or lagging between the stress and strain is called hysteresis loop
Yeah, according to the Hooke's law of elasticity,the stress is proportional to the strain within elastic limit that is Stress ∝ Strain or Stress/Strain = constant. [The constant of proportionality is called as "modulus of elasticity" or "coefficient of elasticity".]
We knew from Hook's law- "stress is proportional to strain." So, stress = k * strain [here, k is a constant] or, stress/strain= k Now, if the stress and strain occurs due to axial force then k is known as modulus of elasticity and it is denoted by E. if the stress and strain occurs due to shear force then k is known as modulus of rigidity and it is denoted by G.
