The article explores how glass plates break under bending using a phase-field fracture model. They compared different fracture formulations, assessed mesh density effects, and validated material properties for polymer foils. The study found that the commonly used fracture model can overestimate the response of thin glass plates. By using different fracture models, they achieved good agreement with measured stresses in laminated glass. The stiffness and resistance of partially fractured laminated glass can be well estimated using a 2D plane-stress model with predefined cracks.
