compressive strain

A multiplication factor of 1.5 is suggested to account for increases in compressive strain from the coarse gravel.

It may become so strong that the thread core buckles when it can no longer withstand the compressive strains.

These form compressive strain fields and tensile strain fields, respectively.

Design methods based on surface rutting concentrate on the vertical compressive strain at subgrade level.

Conversely, compressive strain could be induced by using a solid solution with a smaller lattice constant, such as silicon-carbon.

This can be modeled as a spring-like assembly that has some assumed distribution of compressive strain in the clamped joint components.

Following this theory, the compressive strain in nearby longitudinal reinforcing bars corresponding to complete spalling of surrounding cover concrete is derived.

Flexural vibrations cause alternating tensile and compressive strains to build up on opposite sides of the neutral axis leading to a thermal imbalance.

However, the greater degree of radial compression subjects stoppers to higher levels of compressive strain during and after insertion in the bore of the bottle.

This allows the solute atoms to relieve either tensile or compressive strain in the lattice, which in turn puts the dislocation in a lower energy state.

Although the principal compressive strain is locally greater than 70%, the maximum value obtained for the overall horizontal shortening in a north–south direction is in the range of 40–60%.

Inflow of sodium chloride solutions reduced the swell magnitudes and pressures and even caused the compacted clay specimens to experience compressive strains in oedometer tests.

When soil deforms with no volume change - undrained deformation - the principle tensile strain in the soil exactly equals the principle compressive strain.

Transverse loading causes the member to bend and deflect from its original position, with internal tensile and compressive strains accompanying the change in curvature of the member.

Subsequent compressive strains produced by various local faults including the Hayward Fault folded the lava-bearing rock formations, tilting the Round Top vent complex on its side.

Key words: carbon-fiber-reinforced cement-based composites, structural health monitoring, sensor, electrical resistivity, compressive strain, temperature, moisture content, chloride concentration, fiber volume fraction, water/cementitious ratio, cracking.

To consider cover spalling in analysis, the contribution of cover concrete in a reinforced concrete section is neglected once the compressive strain in nearby reinforcing bars exceeds this value.

Germanium doping of up to 20% in the P-channel MOSFET source and drain causes uniaxial compressive strain in the channel, increasing hole mobility.

The total result is a distortion that involves dilation of the crystal lattice (or unit cell) as a result of tensile and compressive strains, shear strains and rotation.

Current pavement design methods assume that the amount of rutting depends primarily upon the maximum compressive strain caused at subgrade level by the vehicle, and upon the number of strain repetitions.

Specifically, the strain fields of dislocations obey similar laws of attraction and repulsion; in order to reduce overall strain, compressive strains are attracted to tensile strains, and vice versa.

This creates alternating regions of tensile and compressive strain between fingers of the electrode by the piezoelectric effect, producing a mechanical wave at the surface known as a surface acoustic wave.

Molecular dynamics simulations indicate that this rotation occurs to partly relieve a compressive strain developed in the formation of this hexagonal reconstruction, which is nevertheless favored thermodynamically over the unreconstructed structure.

Compressive strain generates vertical splitting cracks in cover concrete that are further widened by the buckling tendency of nearby longitudinal reinforcing bars, which ultimately leads to the spalling of cover concrete.

As a rule of thumb it may be assumed that the prolonged action of stresses less than a quarter of those required for a rapid compressive strain of 10% will not cause more than 1-2% compression.
