Parametric Carpet Plots (CARPET_PLOT)

View Product Datasheet (PDF)

Features

·          Generates carpet plots of laminate properties as a function of percent 0°, +/-45° and 90° plies. 

·         Mechanical properties generated include stiffness, strength and Poisson's ratio.

·         Laminate thermal properties such as coefficient of thermal expansion, conductivity, and specific heat can be generated as well.

·         Identifies laminate percentages (regions) that are governed by fiber failure dominance, by matrix cracking (transverse and shear) dominance and by combined fiber/matrix failure.

·         Applicable to coupon/component levels.

Applications/Benefits:                      

·         Can reduce the number of laminate coupon tests required to verify the entire range of 0°, +/-45° and 90° percentages.

o        Verify select laminate layup predicted strength/stiffness response with physical testing.

o        Then rely on GENOA to generate strength/stiffness responses are all remaining laminate layups.

·         Provides a guideline when test data is not available

·         Identifies laminate layups that are governed by specific local criteria (fiber controlled vs. matrix controlled)
