It was demonstrated that pullulan loading led to increase in the compression modulus and strength and decrease in the cavity size of the materials.
The small strain compression modulus is the same as the small strain tensile modulus only for very small strains.
In addition, it is capable of measuring softening points, thermal expansion coefficients, and compression modulus and can follow modulus-time effects such as creep.
Therefore, the compression modulus of all PP/ZnO nanocomposites was obtained under various levels of strain rates, as shown in Fig.
The compression modulus was measured using the MTS 831 elastomer testing system at optimal t90 cure, 22 hour cure with no service, 22 hour cure with 30 minutes of 11 kg load Doli Flexometer (low severity) service condition, and finally 22 hour cure with 22 kg load (high severity) service condition.
The strain was calculated using the displacement of the crosshead, and the compression modulus was determined from the slope in the elastic portion of the stress-strain curve.
Other areas of note include his devising a novel method for routine measurement of the compression modulus of rubber and his many contributions towards fracture mechanics and nonlinear finite element analysis in the design of robber compounds.
With increased filler content, the compression strength and compression modulus are found to increase linearly.
Shape dramatically affects compression modulus and extremely high compressive moduli are obtainable at high SF.
Because of this low value, the compression modulus of steel changes little with shape factor.
c] is the compression modulus and S is the specimen shape factor, defined as the ratio of the loaded to the total unloaded area.
The compression tests show that the compression modulus increases for lower extent of cure (see Table 1).
