Experimental and numerical crack form simulations of reinforced concrete beam

Abstract

In this thesis, the Concrete Damage Plasticity module in Abaqus is used to determine crack propagation and crack width with a 3d solid model, and a 2d shell model.

Data is given by previous experiments where 6 concrete beams, casted with 3 different mixtures are tested after either 14 days or 28 days. These where loaded into a 4 point bend test, and loaded until failure. Crack widths where measured visually and by camera during the loading, remains the target for this thesis.

Form this dataset, beam 6 was selected, a B35 beam which was tested after 28days.

Along with the test data, material data had been collected by samples casted from the same concrete mixture. These data where used as material input for the Abaqus model.

In addition, material input where extracted from literature.

Results are evaluated for the 3d solid model, and a the 2d shell model.
