Creep is the time-dependent mechanical plastic deformation at high temperatures (usually higher than half of the melting temperature) and stresses far below the yield stress. In both the creep deformation and damage, grain ...

In this study, the effects of silicate based additives on the smart cements, smart cements grouts and drilling muds were investigated. Also the effects of clay soil contamination on the modified smart cement were investigated. ...

Some of the challenges in maintaining the onshore and offshore infrastructures are in monitoring the performance of cementitious materials used in construction and the performance of joints in the storm water pipelines and ...

Constitutive equations establish the relationship between kinetic with kinematic quantities to characterize the specific properties of the material. Mechanical constitutive relations are formulated to describe nonlinear ...

It is critical to ensure the durability of the oil and gas production infrastructures from borehole to pipelines. Rheology properties and hardening characteristics are some of the important parameters for cementing slurry ...

Linear elastic models are often sufficient in the engineering design of structural and mechanical systems. Given that the yield capacity of the material is not reached or exceeded one finds a reasonable design. However, ...

With deeper drilling concern (high in situ pressure and temperature) and increased environmental concerns, there is interest in developing synthetic based drilling fluids. In this study, synthetic based drilling fluids ...
