The tensile stress-strain relationship of rubbers is fairly linear and can be used for obtaining tensile modulusE. In this work we analyzed the tensile stress-strain relationship of filled rubber experimentally and employed the extended 2D homogenization method to compute the modulus of the carbon black (CB) filled rubbers with various CB volume fractions ranging from 5% to 25%. The results reveal that the modulus of CB-filled rubbers increased with the increase in CB volume fraction and in CB aggregation.

In order to systemic study the normalized stress-strain relationship behavior of Yingkou clay. By the consolidated undrained triaxial sherar test of Yingkou clay, obtaining that stress-strain relationship is strain hardening under different confining pressures.A kind of cementation structure in the soil directly affects soft soil strength.And the paper contrast four kinds of normalized factors to study stress-strain characteristics,which are confining pressurethe average consolidation pressureand the ultimate value of principal stress.The results indicate that the normalized degree is more accurate when used value of principal stress and as normalized factor. Meanwhile the normalized stress-strain relationship of Yingkou clay under consolidated undrained condition is established,which can well predict the stress-strain relationship under different confining pressure.

Pva Fiber

Engineered cementitious composites (ECC) has good ductility, with its unique strain hardening and multiple cracking characteristics. Through the research of uniaxial direct tension performance and durability tests of ECC blending with polyvinyl alcohol (PVA) fiber, the tensile stress-strain curves, the freeze-thaw resistances and the impermeability of ECC were analyzed. The tensile stress - strain curve results show strain hardening of ECC achieved under the uniaxial tensile load; PVA fiber has good crack resistance toughening effect, can significantly improve crack resistance and deformation capacity of cementitious composites. The maximum tensile strain of the ECC is between 3800με to 8657με (20-50 times that of polypropylene fiber concrete) displays high toughness and large deformation characteristics. The freezing level of the ECC is higher than F300, which is ideal for the maintenance and reinforcement of concrete structures in cold regions. Domestic and imported PVA fiber can significantly improve the impermeability and crack resistance of the ECC.
