Analytical model of cracking due to rebar corrosion expansion in concrete considering the structure internal force

Analytical model of cracking due to rebar corrosion expansion in concrete considering the structure internal force

Based on the assumptions of uniform corrosion and linear elastic expansion, an analytical model of cracking due to rebar corrosion expansion in concrete was established, which is able to consider the structure internal force. And then, by means of the complex variable function theory and series expa...
