Elastoplastic Modelling of an In Situ Concrete Spalling Experiment Using the Ottosen Failure Criterion

Figure 3

The resulting heater pattern (HH) and preexisting temperature monitoring holes (T) and acoustic emission monitoring holes (AE). The inner 7 m × 7 m square shown is the levelling concrete slab and the outer 8 m × 8 m square is the insulation layer.
