Abstract

This study evaluates Abaqus’s Concrete Damage Plasticity (CDP) model for
simulating the axial stress-strain response of plain and CFRP-wrapped concrete
cylinders. Three specimens from Comber et al.’s full-scale tests were chosen: an
unwrapped cylinder (C-0) and cylinders wrapped with two (C-2) and six (C-6)
CFRP layers. The published load-displacement curves were digitized in
WebPlotDigitizer and processed in Excel to form smooth reference stress-strain
data. Three-dimensional Abaqus/Standard models used a 60 mm hexahedral mesh
for the concrete core and single-element, reduced-integration S4R shells for the
CFRP wrap to speed up the analysis.
