چکیده

Original scientific paper In this paper, the possibility to create uniform porous structure for nonsymmetric precursor heating was investigated together with changes in collapse stress and their reproducibility. The statistic relative standard deviation (RSD) of pore size was used to determine the structural uniformity. It was shown that proper adjustment of the foaming parameters leads to formation of the uniform foam structure. The compression testing showed that standard deviation of collapse stress was higher for uniform structure than those obtained for nonuniform structure.

Strain-rate sensitivity of foam materials: A numerical study using 3D image-based finite element model

Realistic simulations are increasingly demanded to clarify the dynamic behaviour of foam materials, because, on one hand, the significant variability (e.g. 20% scatter band) of foam properties and the lack of reliable dynamic test methods for foams bring particular difficulty to accurately evaluate the strain-rate sensitivity in experiments; while on the other hand numerical models based on ide...

Influence of Different Foaming Conditions on the Mechanical, Physical, and Structural Properties of Polypropylene Foam

In this article, the effects of different foam production times and temperatures on the mechanical, physical, and structural properties of polypropylene (PP) foam has been investigated. The microcellular PP foams were carried out using supercritical carbon dioxide (sc-CO2) as a physical foaming agent in a batch process. The samples were placed in a pressure vessel and were saturated ...

Effect of Structural Height on the Location of Key Element in Progressive Collapse of RC Structures

After the failure of an element in a structure, its loads should be redistributed on the other elements and the structure must provide some new paths to carry the load. If such new load paths are not provided, collapse progression will begin in the structure. As the beginning of progressive collapse in a structure is more sensitive to the missing of an element, the location of that element is m...
