On the Strength of Silicon Carbide Particulate Reinforced Aluminium Alloy Matrix Composites

Mingjiu ZHAO , Yue LIU , Liqing CHEN , Jing BI

材料科学技术（英文）

In the present study, the modified continuum model, quench strengthening and dislocation pile-up model was respectively used to estimate the yield strength of SiCp/Al composites. The experimental results showed that the modified shear lag model or quench strengthening model would underestimate the y...

Repair of Multi Cracks Concrete Sewers Systems

S.Kesteloot , C.Djelal , S.Baraka , I.Benslimane

材料科学技术（英文）

Man-entry sewers sustain many types of structural deterioration, and current repair techniques are very costly. Our objective was therefore to apply methods of localised strengthening by the adhesion of composite plates, as currently used in the construction and public works industry. To do so, it w...
