“…The in-plane modulus however was observed to be approximately 50% of the through-thickness modulus. This contradicts previous test results where the Divinycell PVC H100 foam was observed near isotropic [18,20]. Discussions with DIAB have confirmed that changes in the formulation and manufacturing processes in recent years account for this discrepancy with previous works.…”

“…The through-thickness moduli are very similar to the datasheet (see Table 1). However, the in-plane modulus is approximately 50% of the through-thickness modulus, which does not agree with previous studies where the Divinycell PVC H100 foam was observed near isotropic [18,20]. The Poisson's ratio ν 12 is about twice the value of ν 21 , which satisfies the reciprocity equation:…”

“…This has been identified in material tests [18,20]; however, the in-plane mechanical properties are not available in the datasheet. Therefore another tensile specimen was designed to study the in-plane mechanical properties.…”

A well known foam for naval sandwiches is PVC (polyvinyl chloride) foam. This foam exhibits elasto-damage behavior under tension and elasto-plastic behavior under compression. A proper material model is required for the prediction of the failure and post-failure behavior of these sandwiches during (indirect) underwater explosion loading and blast loading. As material models available did not have combined elasto-plastic and elasto-damage behaviors, a new model needed to be developed. To this end a general thermodynamically consistent framework was used and damage and plastic functional were derived describing the PVC foam behavior. The damage functional contains fracture mechanics properties. Special attention was paid to the compression-tension load reversal of the material model, that may occur during underwater shock loading.

“…To support development of sandwich composite failure models, a series of PVC material tests were performed in Loup et al (2005) to characterize foam core material response under quasistatic and dynamic tension loading. Material stress-strain response was found to be highly nonlinear and dependent on the loading orientation relative to the axis of the foam sheet.…”

Statistically, at least 50% of all injuries experienced by police officers in the line of duty are due to assaults with blunt objects. Therefore, vests used by the police should provide not only good ballistic resistance, but also good protection against such threats. Foamed materials are possible to be used for body protectors or inserts of protective clothes. The effects of dynamic impact with beaters of different shapes onto behaviour of polymeric foamed material were determined. There were used four types of beaters: flat, cylindrical, edgy and cornered. Strikes with blunt objects such as a flat board, baseball bat, edgy brick, pavement brick or a sharp stone, to which a protective ware can be subjected, were simulated. The impact load was applied to the rectangular specimens, made of polyvinyl chloride foam, with a usage of a drop hammer. Plots of force versus compression for all the tested samples were obtained and analysed. The effects of impacts with beaters of different shapes onto foamed material samples were presented. A shape of the blunt object significantly influences crushing behaviour of the foamed material. The impact energy of a flat beater is absorbed effectively on a short distance, since it is spread on a relatively large surface. The cylindrical and edgy beaters did not cause fragmentation of the samples, however, on the upper surfaces of the samples, permanent deformations mapping the beaters shapes as well as some cracks occurred. An impact with a sharp object, for example, a cornered beater is very difficult to be neutralized by the foam material, because it is cumulated on a small area.
