GENOA製品ハイライト

金属、ポリマーとセラミック複合材の等価材料特性:Equivalent Material Properties of Metallic, Polymer and Ceramic Composites
  • GENOA determines material strength, moduli, moisture, thermal, and heat conductivity properties. Degradation of material properties to environmental (moisture, thermal), and manufacturing (defects, residual strains) is included.
耐久性と損傷トレランス:Durability & Damage Tolerance
  • GENOA evaluates the material/structural response, including: life cycle, degradation of material properties due to initiation, location of failure, and growth of damage under in-service operations and environments (static, dynamic, thermal, creep, impact, and low/high/random frequency cyclic fatigue). GENOA identifies the percent contribution of various possible composite failure modes. GENOA predicts the inspection interval, incipient damage locations, and margin of safety.
製造可能性:Manufacturability
  • GENOA accounts for minimum defect occurrences (i.e. voids (shape, size), buckling, wrinkling), fiber jamming, and fiber volume fraction. It can handle precision manufacturing, smart materials and processes, and smart structures. GENOA can determine the best fit to a shape as well as optimum aeroelastic fiber angle orientations.
仮想試験ツール:Virtual Testing Tool
  • GENOA virtually duplicates the experimental testing process. It can computationally replicate photoelasticity, far field strains, material fracture parameters, strain gage readings, and margin of safety calculations.
確率的な破損解析:Probabilistic Failure Analysis
  • GENOA’s Probabilistic Failure Analysis: Identifies progressive damage parameters and their sensitivity; Evaluates the uncertainty of material strength to material parameters; Determines sensitivities of failure modes to design parameters to facilitate targeting design parameter changes that will be most effective in reducing probability of a given failure mode from occurring, and: calculates the probability of failure.

Tape/Braid/fabrics (material selection and Analysts)
  • No detailed FE models required
  • May require braid angle information from micro-graphs for the Braid and fabrics
Laminate A- & B-Basis Allowables (for material certification and qualification)
  • Potential to save 40 to 60% coupon testing
  • May require input from ASTM standard Unidirectional laminate test data (ply properties)
Reverse Engineer unknown values (ply/fiber/matrix) using in-plane ply properties (FE Analysts)
  • Predict effective constituent (fiber and matrix) modulus, Poisson’s ratio and strength properties from ply properties
  • Additional information such as fiber and void volume ratio is required as input. Also fiber modulus available from vendor is required as input
Account for material nonlinearity for improved accuracy (FE Analysts)
  • Predicts effective matrix nonlinearity that results in laminate level nonlinearity from in-plane shear and transverse compression ASTM standard tests
  • Requires full stress-strain data from tests for in-plane shear and transverse compression and tension
Parametric carpet plot (Designers and material selection)
  • Generates laminate material properties plot as a function of angled ply distribution through-the-thickness
  • Requires limited test data for validation for couple of laminates
Sandwich Material properties (FE Analysts)
  • Predicts material properties for sandwich materials (foam + composites, honeycomb + composites, composites + metals [GLARE, CentrAl], etc)
  • Requires basic ASTM standard coupon testing for individual constituent. Note that composite can be at ply level, metal from MMPDS/Mil-HDBK 5H, foam/Honeycomb from literature/vendor
Generate input (unknown material properties) for other well known FE solvers (MD NASTRAN, NEi NASTRAN, ABAQUS, LS-DYNA, ANSYS, Fire Hole, ESAComp and others) (FE Analysts and designers)
  • In-Situ Fiber/matrix properties. Fiber is assumed to be transversely isotropic or isotropic and matrix as isotropic
  • Predicts apparent out-of-plane properties for the fiber and ply using only in-plane ply test data
  • Need Ply test data as input
14 Test Validation Cases
  • Several different material systems ranging from low modulus low strength matrix and fiber to high modulus and high strength fibers
