GENOA Overview

- Durability & Damage Tolerance (D&DT)
- Reliability and Life Prediction
- Enhances FEA and Augment Results for NASTRAN, ABAQUS, LS-DYNA & ANSYS

GENOA is a stand-alone and/or web based integrated structural analysis/design software suite developed to cost effectively predict strength, reliability and durability of aerospace structural components at the design stage with minimal experimental testing support.

GENOA Multi-scale progressive failure analysis predicts the crack initiation, growth, and final failure of monolithic and 2D/3D braided/ laminated/ stitched/ woven composite materials. It evaluates the structural and material response including degradation of material properties due to initiation and growth of damage under static, dynamic, thermal, impact, creep, and low/high frequency cyclic fatigue loading conditions.

Key Features

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.

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.

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.

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.

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.

Product Modules

GENOA is a modular software dealing with linear and non-linear technology. The software suite integrates a variety of modules for your analysis needs.

Progressive Failure Analysis (PFA)
PFA is an integrated structural analysis/design software that predicts strength, reliability and durability of structural components at the design stage with minimal experimental testing support.

Progressive Failure Dynamic Analysis (PFDA)
PFDA performs progressive failure analysis on composite structures using an explicit transient dynamic algorithm.

Virtual Crack Closure Technique (VCCT) & Discrete Cohesive Zone Model (DCZM)
Virtual Crack Closure Technique (VCCT) and Discrete Cohesive Zone Model (DCZM) are fracture mechanics based approaches for progressive crack growth analysis.

Material Constituent Analysis (MCA)
MCA is a 2D/3D composites (i.e., Laminated, Woven, and Stitched) analyzer, that was originally developed at NASA/Glenn Research Center.

Material Uncertainty Analysis (MUA)
MUA combines composite micro-mechanics and probabilistic analysis to evaluate composite material reliability from the scatter of measured fundamental primitive variables.

Material Characterization Optimization (MCO)
MCO is an integrated material characterization/optimization tool that can reverse-engineer structural and material behavior.

Filament Winding (FW)
FW designs and analyzes composite over-wrapped pressure vessels (COPV's). It is based on advanced NASA composite mechanics codes combined with a special module for filament winding analysis.

For more information, please refer to the Datasheets of the modules.

Software Package

In addition to the analysis modules, GENOA also includes an extensive library of example models and materials.

GENOA Standard Installation Package
This is the standard installation package that includes the Java based GUI, the analysis modules, documentation, and Step-by-Step examples with only their input files.

Code Verification Examples Package
This package includes a variety of verified examples and validation against test data in different formats including ABAQUS, ANSYS, NASTRAN, etc.

Building Block Examples Package
This includes a diverse collection of models demonstrating different modules, different model structures, and Industrial Verification examples.

ASTM Examples Package
This package contains FEM's of twelve American Society for Testing and Materials (ASTM) specimens that are used as examples for predicting composite material properties using GENOA's PFA. The ASTM models include tension, compression, in-plane shear, bending, interlaminar tension/shear and fracture response coupons.

For more information on the software package, please refer to the Frequently Asked Questions section.

Installation and Platforms

GENOA utilizes Java for an enriched Graphical User Interface (GUI) and stand-alone Fortran/C++ compiled executables for analysis. GENOA requires Java 1.5 and Java3D 1.3.1 for 3D graphic model displaying. GENOA runs on Windows 2000, Windows XP and Linux platforms. GENOA reads NASTRAN, ABAQUS, ANSYS and MHOST (Default) input datasets. It can use NASTRAN, MARC, ABAQUS, ANSYS, LS-DYNA, or MHOST (Default) as the finite element solvers
