Characterization of polyacrylonitrile ultrafiltration membranes
Get PDFVarious methods have been used to characterize ultrafiltration membranes, such as gas flux measurements, (field emission) scanning electron microscopy, permporometry and liquid-liquid displacement. Significant differences in the pore size distributions determined from permporometry and liquid-liquid displacement were found
Analysis of reinforced concrete structures with occurrence of discrete cracks at arbitrary positions
Get PDFA nonlinear analysis of in-plane loaded plates is presented, which eliminates the disadvantages of the smeared crack approach. The elements used and the computational method are discussed. An example is shown in which one or more discrete cracks are dominant
