If a crack does occur due to stress or fatigue, the multiple plies will contain pressure, and hold the joint in place. In doing this, the plies act as a labyrinth seal, which is a mechanical seal that fits around an axle and prevents leaks. A small bubble or blister occurs in the ...
The boundary values of two sample problems, have been determined by solving this integral equation. To calculate the propagation of the displacement field in the region for any axially symmetric problem, a second elastodynamic state has also been derived. This new elastodynamic state has been used ...
2.2 One-Dimensional Stress Strain Temperature Equation In the case of one-dimensional problems, there is only one observable state variable q, i.e. the axial strainε and the generalized force Q corresponds to the axial stress σ. From eq. (6) we have a one-dimensional non-linear thermo-...

(2) When stretching, each stretching point should be able to meet the tangent line along the edge of the sample freedom of movement; (3) There are enough tensile points to make the specimen evenly stretch and deform; (4) The selection of the stress-strain measurement range should be consid...
aIn order to analyze the reinforcing effect on the soil response at low axial strains, it is assumed that: (1) The column and the soil are linearly elastic; and (2) the radial stress at any point Of the reinforced soil sample is equal to the applied total lateral pressure vR . These ...

So far all our discussions have dealt with statics. In dynamic problems, any type of viscosity η of the material (present in models for creep,viscoelasticity, or viscoplasticity) implies a characteristic length. Indeed, since η = stress/strain rate ˜ kg/m s, and theYoung's modulusEand...
Figure 19 shows a sample mean stress distribution in the longitudinal section of a part obtained from rolling with two flat wedges. The analysis of the data shown in the figure proves that the areas of the material in which positive (tensile) mean stresses σm occur are located around the ...
