This paper focuses on the flexural behavior of masonry walls strengthened with precast engineered cementitious composite (ECC) sheet. The were subjected to out-of-plane static loading and analyzed using ABAQUS. For validation numerical results, four size 762 × 480 230 mm cast burnt clay bricks cement mortar. Out four, two ECC sheet epoxy as adhesive, remaining acted control specimens. results experimental shows that model can effectively capture nonlinear predict strength failure mechanism....

Abstract Oil well cement (OWC) are widely used in oil industry both exploration and production of gas. The purpose OWC is to seal the annular space between metal casing walls a borehole. has other application such as grouting repair offshore structure, cementing wells likes water, waste disposal, geothermal, injection or storage. There numerous problems high temperature pressure downhole condition well. slurry undergoes reduction strength (strength retrogression) with time when exposed...

This study deals with development of a composite mechanics-based design approach for flexural strengthening masonry walls using different layers fiber-reinforced polymer (FRP) strips externally bonded and/or near surface mounted (NSM) FRP bars. To verify the developed approach, experimental was also conducted on three groups walls. Six burnt clay brick size 780 × 480 230 mm were fabricated. Out six, four are strengthened combination longitudinal carbon and horizontal NSM The responses these...

Abstract The fluid invasion basically gas in the cement column is a worldwide problem. This one of main challenges oil well industries to protect wellbore from invasion. problem has recognized mid 1970 and basic technologies associated with it not changed significantly. leakage can cause catastrophic events such as blow out contamination adjacent aquifer layers leading environmental concerns. Although much effort been put forth on migration issues, but no efficient solutions have established...

In this paper, a computational approach based on kinematic model for laminated composite I-section beam is presented. The flexural behavior of I-beams analyzed by using Classical Lamination Plate Theory (CLPT) and the First Order Shear Deformation (FSDT). Based these theories, computer programme analysis I-beam has been developed in MATLAB. comparison results obtained both theories made. It shown that shear deformation significant effect deflection beam. Furthermore, also modeled ABAQUS...
