Conveyors consist of rubber coated, fiber reinforced belts which are supported and driven by rollers. The rollers are generally coated to increase and stabilize the friction and to reduce abrasion, noise and dirt buildup. Pressures and shear stresses

An overview of the causes and effects of porosity in rubber has been presented. The formation of porosity in rubber can be attributed to the heterogeneous nucleation and diffusion controlled bubble growth. The process proceeds simultaneously with vul

Cylindrical samples, with different shape factors and levels of porosity, were prepared from a model EPDM compound and tested in compression. The modulus was reduced considerably with the introduction of porosity, especially when the shape factor was

The advantage of the constant-speed squeeze film flow is that the shear rate is not constant but changes with gap height and position. This allows the rheological characterization of a material to be carried out in a shorter amount of experimentation

The applicability of the squeeze film flow geometry in a processibility tester is investigated in this study. A prototype processibility tester has been built by retrofitting it to a servohydraulic load frame. Several processibility parameters such a

It has been shown that it is possible to predict the viscoelastic response of elastomers and elastomeric engineering components under both load- and position-control conditions if one assumes: a) that the modulus of the materials increases with the s

The influence of carbon black loading on the dynamic properties of statically deformed elastomers has been investigated. The energy loss per cycle was found to increase according to the square of the strain amplification factor as expressed by the Gu

Rubber has a stress-strain response to compression-shear loadings that is the same as its stress-strain response to simple shear loadings. However, its load-deflection response to the compression-shear loading is not the same as its simple shear resp

The constant load buckling of viscoelastic columns has been studied extensively in the past and equations have been derived to predict the buckling time from the geometry of the columns and the constitutive equation of the material. These theories re

The buckling of viscoelastic columns has been considered from both a theoretical and an experimental perspective. The fact that buckling occurs at relatively low strain where the SBR is nearly linearly viscoelastic allowed several simplifications in
