Composite Damage (CompDam) Progressive Damage Analysis Software
The Composite Damage (CompDam) Progressive Damage Analysis software is developed for the prediction of damage onset, damage progression and structural collapse of structures manufactured of fiber-reinforced plastic laminates. The emphasis has been on development of an analysis capability for application at the structural level. Hence, modeling of damage progression is undertaken at the meso-scale, where each ply of a laminate is represented as a homogenous orthotropic continuum. All of the composite damage mechanisms (matrix cracking, fiber breaking and kinking, and delamination) and their interactions are represented. The CompDam software is implemented as user written subroutines for use with the Abaqus commercial finite element code. Input for CompDam includes ply-level material properties, and interface properties obtained from standard material characterization tests. The output from CompDam includes damage variables associated with each damage mode. These damage variables describe the evolution of damage and are used to generate updated structural constitutive matrices and load redistribution as damage evolves.

Predict the Behavior of Blackbody Heated Surfaces
<p>Many areas of science and engineering require an understanding of the radiation that emits from a heated surface. Specifically, there is a need to calculate the radiation's intensity and spectral distribution for thermal radiation heat transfer, infrared signature analysis, and radiation thermometry. Furthermore, being able to predict the heat transfer rate and the spectral distribution of the emitted energy for the blackbody is particularly helpful.</p> <p>The need for these capabilities led researchers at NASA's Armstrong Flight Research Center to develop a set of computer functions that can be used in predicting the behavior of heated surfaces. In addition, the routines enable engineers to use information regarding spectral intensities to determine surface temperatures. They can also calculate the sensitivity of these temperature measurements to unknowns in the input parameters. NASA wrote these routines in Microsoft&#174; Visual Basic&#174; for Applications (VBA) software and incorporated functions specific to Microsoft Excel&#174; software.</p> <p>BENEFITS</p> <p> * Full spectrum: Enables calculation of important function derivatives and integration of the blackbody function over a range of wavelengths</p> <p> * Portable: Can be integrated with other engineering software</p> <p> * Easy to use: Based on widely available computer software tools from the Microsoft suite</p> <p>POTENTIAL APPLICATIONS</p> <p>In addition to aerospace applications, this software is useful for researchers developing new materials and other technologies to be used in a wide range of applications:</p> <p> * Thermal management: Integrated circuits, computer chassis, remote sensors</p> <p> * Heat shields: Automotive, appliances, safety equipment</p> <p> * Insulation: Architecture, textiles/clothing</p> <p> * Energy storage: Collecting/Storing thermal energy</p> <p> * Monitoring: Infrared-based surveillance</p> <p> * Earth/Planetary science: Understanding the composition of clouds, volcanoes, etc.</p> <p>Microsoft, Visual Basic, and Excel are registered trademarks of Microsoft Corporation in the United States and/or other countries.</p>

MATLAB Software Associated with "Practical Micromechanics of Composite Materials" Book, Elsevier Publishing
This MATLAB software toolset was developed for use in solving the example and exercises provided in the book entitled "Practical Micromechanics of Composite Materials" , authored by Prof. J Aboudi, S. M. Arnold and B.A. Bednarcyk. The MATLAB scripts and functions calculate composite effective properties, margins of safety, and progressive damage of unidirectional and/or composite laminates using classical ply-based lamination theory, stand-alone micromechanics theories (such as Mori-Tanka, MOC,GMC, HFGMC along with failure theories and margin of safety calculations) or micromechanics-based classical lamination theory to illustrate their utility for the design and analysis of advanced composites.

T0TEM - T0 Test Evaluation Module
The T0TEM (T0 Test Evaluation Module) is an analysis software for transition temperature tests performed under ASTM E1921 - Standard Test Method for Determination of Reference Temperature, To, for Ferritic Steels in the Transition Range. T0 is the temperature at which a ferritic steel transitions from mostly ductile tearing to unstable cleavage failure mode. This software analyzes test results to determine T0, the master curve, confidence bounds, validity, margin adjustment and inhomogeneity by simple, bi-modal, and multi-modal methods. T0TEM also allows for batch analysis, raw data output and plot creation.

Porous Microstructure Analysis (PuMA)
The Porous Microstructure Analysis (PuMA) software has been developed in order to compute effective material properties and perform material response simulations on digitized microstructures of porous media. PuMA is able to import digital three-dimensional images obtained from X-ray microtomography or to generate artificial microstructures that mimic real materials. PuMA also provides a module for interactive 3D visualizations. Version 3 includes modules to compute simple morphological properties such as porosity, volume fractions, pore diameter, and specific surface area. Additional capabilities include the determination of effective thermal and electrical conductivity (including the ability to simulate local anisotropy), effective diffusivity and tortuosity from the continuum to the rarefied regime, and techniques to determine local material orientation.

MicroStructPy - A Microstructure Mesh Generator for Heterogeneous Materials
This technology is software that generates meshes of materials composed of dissimilar constituents. Example materials include carbon fiber composites, metallic alloys, ceramics, and rocks. These meshes are unstructured, meaning the mesh elements are triangular in 2D and tetrahedral in 3D. The mesh generator has the following capabilities -2D and 3D domains -Mesh quality controls -Multiple constituents/phases -User-defined grain size distributions -Highly eccentric grain shapes -Preferred grain orientation -Preferred grain positions -Multiple instances of the same microstructure

Tool for Analysis of Surface Cracks (TASC)
Created using the commercial math analysis software MATLAB, TASC enables the easy computation of nonlinear J-integral solutions for surface-cracked plates in tension by accessing and interpolating between the 600 nonlinear surface crack solutions documented in NASA/TP-2011-217480. The only required inputs to the program are the surface crack dimensions, plate cross-section dimensions, and material properties. TASC provides a convenient and easy-to-use interface for the solution set that allows a novice user to obtain a fast and reliable fracture toughness solution.
