Energy dissipation and strength evolution of ultra-high- performance fiber-reinforced concrete (UHPFRC)

Ellis, Brett / Zhou, Min / McDowell, David L.

A fully dynamic 3D mesoscale model was developed to quantify the energy dissipation and load-carrying capabilities of Ultra-High-Performance Fiber-Reinforced Concrete (UHPFRC) subjected to compression at strain rates of 500 - 1,000 s^-1 under conditions of nominal plane strain. This model accounts for three constituents: porosity, fibers, and cementitlous matrix. Microstructure instantiations encompass a range of pore volume fraction (1-10%), pore diameter (0.2-0.4 mm), fiber volume fraction (0-4%), and fibermatrix interfacial bonding strength (1-2 MPa). Calculations delineate and characterize the evolution of kinetic energy, strain energy, work expended on interfacial damage and failure, frictional dissipation along interfaces, and bulk dissipation through granular flow as functions of microstructure (constituent spatial distributions), loading, and constituent properties.
