In addition to these three models, Model 4 as shown in Figure 3 (elastic-plastic model) was included, which assumes that the metal plate behaves elastically with linear stress distribution and plywood behaves plastically. By summing the forces and moments in the diagram of Model 4, equations for estimating moment capacities of Models 4 are:
The cracks are formed preferentially along the grain boundaries and the material at the worn surface is observed to be plastically deformed.
Since the size of the plastically deformed bond-pad contact area is directly proportional to contact pressure, the tip shape also contributes to [C.sub.RES].
X-ray diffraction strain measurements revealed that the strain in the nickel layer annealed at 500 K, at room temperature is close to this value, which suggests that the thermal strains are hardly plastically relaxed, and consequently, not many dislocations are formed during cooling down.
This implies that vehicles that do not sustain permanent damage in low-speed impacts produce correspondingly higher dynamic loadings on their occupants than those that deform plastically under the same or possibly more severe impact conditions.
Meshing--some of the early meshes were too coarse to make up the curvature that occurred as members deformed plastically and buckled locally.
One sees this theology of culture gaining its assimilative power when advertising plastically co-opts any hermeneutical framework that might threaten theocapitalism, redeploying it in the process with the dignity afforded all possibly subversive hermeneutics: as a means of strategic advance under cover of liberal, pluralist values: advertising that advances its cause by way of religious inclusiveness, of affirming women, or of multiculturalism.
Paul Meade was striking as the prancing, plastically gallant Ashburningham.
A nonideal spring stretched too far deforms plastically and bends.
Diapirism, where a large blob of magma squeezes upward through plastically deforming surroundings, is favoured when the magma is very viscous and the crust is ductile.
The oceans are far more plastically fluid than the underlying lithosphere and magma, so, if all the Earth ceased its rotation within a short period of time, all that seawater deprived of centrifugal force will want to flow poleward to achieve a dynamic equilibrium.
