engineering ceramics due to high-strength-to-weight ratio, wear and corrosion resistance, and high strength temperatures, in the industries especially in aerospace, automobile, electronics and computers are used widely. in attention to the  increasingly usage process of these material, applying of conventional machining methods  for producing  machined into complex and desired shapes or making ...

in this study, the vibration of cracked plates is investigated using the differential quadrature method and experimental modal analysis. the crack, which is assumed to be open, is modeled by the extended rotational spring. with its finite length, the crack divides the plate into six segments. then, the differential quadrature is applied to the governing differential equations of motion and the ...

In India the enormous loss of life and property perceived in last couple decades, attributable to failure structures instigated by earthquakes. Responsiveness is now being given assessment sufficiency strength framed RCC resist solid ground motions. The seismic reaction building frame terms performance point earthquake forces on Reinforced with help pushover analysis carried out this project. m...

Background: A steel frame system becomes structurally less efficient when subjected to large lateral loads such as a strong wind, earthquake. Many research efforts have been made develop more structural systems with better resistance against loads. Methods: An attempt is in this direction by both analytical and experimental studies. bare framed model of size 4m x4m chosen for G+2 storey columns...
