On the elastic and mixed-mode fracture properties of PVC foam

Sandwich structures are widely used for the design and fabrication of lightweight structural systems, due to their capability exhibit excellent thermal performances at low material usage. Understanding phenomena propagation macro-cracks in core delamination face-to-core interface aspects great computational interest. Linking sophisticated models with actual characterisation mechanical properties is essential view real engineering applications. The elastic fracture materials composing particularly relevant because its cracking affects capacity sandwich carry out transverse loads. In this work, PVC foams typically as inner applications investigated over a range foam densities. Firstly, under compressive uniaxial loading measured using full-field methodology. Subsequently, Semi-Circular specimens tested bending varying position supports generate all mixed modes. Suitable criteria also considered order assess evaluate parameters foams. Finally, experimentally determined have been validate response provided by numerical model developed authors.
