Modeling and estimation of deformation behavior of particle-reinforced metal–matrix composite

investigation of gassing behavior, electric and dielectric properties of different insulating fluids.

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...

Research on Deformation Behavior of Reinforced Concrete Composite Shear Wall with Concealed Bracings Based on Performamce

Article history: Received: 14.5.2014. Received in revised form: 20.1.2015. Accepted: 14.5.2015. In order to determine the deformation capacity of reinforced concrete composite shear wall with concealed bracings at different performance levels, some previous research of domestic scholars are reviewed by analyzing 89 shear wall specimens using a performance-based seismic design method. The perfor...

Strain gradient effects on deformation strengthening behavior of particle reinforced metal matrix composites

Dislocation models with considering the mismatch of elastic modulus between matrix and reinforcing particles are used to determine the effective strain gradient h for particle reinforced metal matrix composites (MMCp) in the present research. Based on Taylor relation and the kinetics of dislocation multiplication, glide and annihilation, a strain gradient dependent constitutive equation is deve...

nonlinear deformation analysis and modeling of composite with aluminum layers

fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new materi...
