CFS Software \u2013 The Closed Form Shifting Algorithm<\/strong><\/p>\n

Principle<\/strong><\/em><\/p>\n

CFS[1]<\/sup> Software is intended for automated construction of master curves, representing\u00a0long term behaviour of material, from a set of short term measurements (material\u00a0function segments) performed at different constant temperatures (or pressures).<\/p>\n

Results<\/strong><\/em><\/p>\n

    \n
  • Shift factors at different reference temperatures;<\/li>\n
  • Isothermal (isobaric) master curve and isochronal curve at selected reference\u00a0conditions.<\/li>\n<\/ul>\n

    Principle<\/strong><\/em><\/p>\n

    DAB[2]\u00a0<\/sup>Software is intended for quantitative analysis of strain accumulation when\u00a0exposed to tooth-like periodic shear stress loading of certain intensity in specific\u00a0location on the tooth of the belt.<\/p>\n

    Results<\/strong><\/em><\/p>\n

      \n
    • cumulative accumulated strain for selected number of loading cycles;<\/li>\n

      INTERCONVERSION Software<\/strong><\/p>\n

      Principle<\/strong><\/em><\/p>\n

      INTERCONVERSION[3]<\/sup> Software is intended for different interconversions among\u00a0viscoelastic material functions.<\/p>\n

      Capabilities<\/p>\n

        \n
      • interconversion (using different numerical methods);<\/li>\n
      • among static material functions (Hopkins-Hamming method);<\/li>\n
      • static to dynamic material function and conversely (Schwarzl method);<\/li>\n
