2D Multi-scale Simulation and Homogenization of Foamed Concrete Containing Rubber Bars

One of new innovation in modified concrete is foamed concrete containing rubber bars. The function of rubber on foamed concrete is to improve the strength and enhance the resistance toward high strain rate loadings. The production of foamed concrete containing rubber bars, therefore, leads to the he...
