Hydrostatic compression on polypropylene foam
Models currently used to simulate the impact behaviour of polymeric foam at high strain rates use data from mechanical tests. Uniaxial compression is the most common mechanical test used, but the results from this test alone are insufficient to characterise the foam response to three-dimensional stress states. A new experimental apparatus for the study of the foam behaviour under a state of hyd...
متن کاملSynthesis and Optimization of Submarine Pipeline Routes
Traditionally, the selection of a pipeline route for offshore applications has been manually performed by the engineer, by a quick inspection of the seabottom bathymetry and the available information regarding obstacles. Eventually the evaluation of a given route could be performed using analysis tools, but in any case the process is highly dependent on the expertise of the engineer. In this co...
متن کاملEntangling additives enhance polypropylene foam quality
Linear polypropylene (PP)—composed of long polymer chains devoid of branches or crosslinked structure—and blends of PP with olefinic elastomers are widely used in the automotive and packaging industries. What makes foams produced with these materials of growing interest is their potential to replace the prevalent thermoset polyurethane foams which are not recyclable. However, the production of ...
متن کاملAir-Coupled Piezoelectric Transducers with Active Polypropylene Foam Matching Layers
This work presents the design, construction and characterization of air-coupled piezoelectric transducers using 1-3 connectivity piezocomposite disks with a stack of matching layers being the outer one an active quarter wavelength layer made of polypropylene foam ferroelectret film. This kind of material has shown a stable piezoelectric response together with a very low acoustic impedance (<0.1...
متن کاملArtificial Neural Networks for Coastal and Ocean studies
Artificial neural network (ANN) is a major tool in artificial intelligence computing and it is also extensively used across all disciplines of coastal and ocean engineering including offshore, deep-ocean and marine engineering. A review of important research studies reported so far in these areas is presented. ANN in general has provided either substitutive or complementary option to traditiona...
