Basic Module: Provides the linear analysis functionality:

  • Curing, Hygroscopic, Thermal and Mechanical loadings
  • Mechanical loading defined by Load/Moment and/or Strain/Curvature components
  • Effects of manufacturing deviations from the nominal fiber volume fraction
  • Main results include effective stiffness constants for the laminate, effective hygroscopic and thermal coefficients, solution matrices and vectors, expected in-plane laminate strength
  • Layer stress and strain can be examined in the global or fiber axis systems
  • Built-in failure criteria are Tsai-Wu, Tsai-Hill, Hoffman, maximum/minimum stress
  • Displaced shape in 3D
  • Off-axis laminate behavior demonstrated by polar plots of effective laminate stiffness and hygrothermal coefficients

Design Module: Introduces a new dimension to LAP, in two variants: The Laminate Design procedure consists of specifying a set of mechanical loadings, each with stiffness and strength constraints which must be satisfied by an optimum symmetric laminate to be designed. LAP carries out a thorough investigation of the candidate stacking sequences and presents a finite set to the user. With Batch Solution, a number of laminates are examined to confirm that they indeed satisfy the stiffness and strength requirements set by the user.

Non-linear Module: Includes effects of non-linear material stiffness.

Additional Failure Criteria Module: The BFS failure criterion (Budiansky-Fleck-Soutis) is used to calculate the unnotched as well as the notched longitudinal compressive strength for a laminate. The notch geometry can be one of: center notch, edge notch, open hole, countersunk hole, or filled hole. Through a user-supplied function, a custom failure criterion can be defined for use with linear or non-linear strength analysis.

In addition to LAP, Anaglyph also has included their Component Design Analysis (CoDA) software through the APA. Learn More
