Microcracking in Concrete

Microcracking in Concrete

Microcracking in concrete refers to the tiny cracks that can form within the material even before any external load is applied. These microcracks typically occur at the interface between the coarse aggregate and the hydrated cement paste, often as a result of differential volume changes prompted by variations in stress-strain behavior, as well as thermal and moisture movement. Initially, these microcracks remain stable and do not grow substantially until the concrete is stressed to about 30...

Background:

Understanding enamel/adhesive interface integrity is crucial for dental restoration longevity.
Micro-crack propagation can lead to adhesive debonding and restoration failure.
Current simulation methods may not fully capture complex interfacial failure mechanisms.

Purpose of the Study:

To investigate micro-crack propagation at the enamel/adhesive interface using advanced finite element (FE) techniques.
To develop and validate a 3D FE submodeling approach for simulating interfacial fracture.
To analyze stress concentrations and predict crack paths in dental adhesive bonds.

Main Methods:

Generation and analysis of a 3D FE macro-model of enamel/adhesive/ceramic under shear load.
Construction of a 3D FE micro-model at the enamel/adhesive interface, incorporating resin tag morphology.
Application of element death technique and custom iterative code for micro-crack propagation simulation.
Validation of FE simulation results through parallel in vitro experiments.

Main Results:

Stress concentration identified at the upper corner of the enamel/adhesive interface and the resin tag base.
Simulated fracture path observed along the resin tag base and the enamel/adhesive interface.
Experimental fracture patterns closely corresponded with simulation predictions.
FE submodeling accurately depicted 3D micro-stress patterns and crack propagation.

Conclusions:

Finite element (FE) submodeling combined with the element death technique is effective for simulating 3D micro-stress and crack propagation at the enamel/adhesive interface.
This validated FE approach provides a powerful tool for understanding and predicting failure mechanisms in dental adhesive bonds.
The study highlights the importance of interfacial morphology, such as resin tags, in influencing crack propagation and bond strength.
