Free-Edge Effect On The Effective Stiffness Of Single-Layer Triaxially Braided Composite, Chao Zhang, Wieslaw Binienda, Robert Goldberg

Free-edge effect is known to play an important role in the failure of triaxially braided composites, especially under transverse tension loading conditions. However, there is little understanding available regarding the free-edge effect on the elastic property of the material. The emphasis of the present study is to examine the impact of the free-edge effect on the effective elastic response of a single-layer triaxially braided composite. Transverse tension straight-sided coupon specimens with various widths are tested and analyzed. The experimental results demonstrate an obvious increase in the tangent modulus and failure strength as the specimen width increases. The surface out-of-plane displacement …
Prediction Of Unconfined Compressive Strength Of Pulverized Fuel Ash-Cement-Sand Mixture
Prediction Of Unconfined Compressive Strength Of Pulverized Fuel Ash-Cement-Sand Mixture
Faculty of Engineering University of Malaya
Recently, ground improvement has become much more feasible. Chemical stabilization is a quick and affordable approach to enhancing soil characteristics. An important avenue of research is discovering alternative materials for use in soil enhancement. Pulverized fuel ash (PFA), which is a waste byproduct of coal power plants, has been shown to reduce the environmental risks and costs involved in construction. In this study, a series of unconfined compressive tests were performed for various mixtures of cement, PFA, and sand; the tests considered both the curing period and the optimum moisture content (OMC). In addition, multiple variable linear regression was used …
