They'll bleat and baa, dona like goats, Gorge down black sheep, and strain at
motes, Array their backs in fine black coats, Then seize their negroes by their throats, And choke, for heavenly union.
When one compresses an elastomer to a given strain at
room temperature, the initial load will depend on the rate at which it is compressed, after which the load will decrease over time to an equilibrium elastic load.
Automated electron backscatter diffraction measurements have revealed both the extent of the elastic strain field in the neighborhood of an oxide growth front as well as the magnitude of elastic strain at
any position in that field.
mean strain at
three strain widths of 3%, 5%, and 7%, respectively, at different numbers of cycles.
In such a case, the stress-strain relation can be inverted and strain at
time t is characterized by:
These curves illustrate the danger of drawing conclusions based only on the values of S-300, tensile strength and strain at
This shows a strong relation between the strain at
failure of an elastomer and an increase in the A/I ratio.
t/[tau]) where: t = time; [tau] = relaxation time; [epsilon] = the strain at
any given time
Failures are often related to high amplitude strain at
resonance, and seldom related to high amplitude inputs at frequencies well removed from the isolator natural frequency.
