Novel fatigue strengthening solution for metallic structures using adhesively bonded Fe-SMA strips: A proof of concept study
نویسندگان
چکیده
An innovative fatigue strengthening solution for metallic structures that takes advantage of the shape memory effect an iron-based alloy (Fe-SMA) and bridging mechanism offered by bonding technique has been proposed examined. Fatigue tests on cracked steel plates with bonded carbon fiber-reinforced polymer (CFRP) nonprestressed prestressed Fe-SMA strips were conducted. The experimental results demonstrate are much more effective than CFRP strips, extending crack growth life a factor 3.51. is highly in retarding structures.

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
15 صفحه اولDesign Analysis of Adhesively Bonded Structures
The existing analytical solutions for the peeling and shearing stresses in polymeric adhesively bonded structures are either too inaccurate or too complex for adoption by practicing engineers. This manuscript presents a closed-form solution that is reasonably accurate yet simple and concise enough to be adopted by practicing engineers for design analysis and exploration. Analysis of these conci...

This paper presents a structural health monitoring technique based on analysis of the dynamic signature of the structure, which changes as damage occurs, due to alterations in structural properties such as stiffness and damping. Experiments performed on plate specimens and T-joint specimens which had various degrees of damage in the form of delaminations showed that it is possible to quantify t...

متن کاملFatigue strengthening of riveted girders in a historic railway metallic bridge in Switzerland using pre-stressed un-bonded CFRP laminates
In this paper, the applicability of the constant life diagram (CLD) methodology for fatigue strengthening of metallic members is described. The CLD methodology is a method that uses the combined effect of alternating stress, mean stress and material properties to predict the material life-time under high-cycle fatigue loading. The method could be used most efficiently to improve resistance to c...
