Influence of Specimen Width on Crack Propagation Process in Lightly Reinforced Concrete Beams.
Materials (Basel)
November 2024
Article Synopsis
- Traditional 2D models for studying concrete fractures often overlook how specimen width affects crack behavior, particularly in reinforced concrete beams with varying crack lengths.
- A 3D numerical method was developed to simulate crack propagation in lightly reinforced concrete beams, utilizing nonlinear spring elements to accurately represent concrete softening and bond-slip between steel and concrete.
- Comparisons with experimental data showed that the 3D model provided more accurate load-displacement curves, revealing that 2D models significantly overestimate external loads during the initial loading stage.
The strength anisotropy for inherent anisotropic rocks presents a challenge to simulate considering the influence of intermediate principal stress. Based on the modified Lade failure criterion, a new anisotropic modified Lade criterion combining an empirical equation is established and verified using published experimental datasets of anisotropic rocks. The incremental constitutive model for anisotropic rocks is derived by using finite difference theory.
