  1. TexGen4SC Tutorial #1: Homogenization Analysis of Textile Composites with Arbitrary Inter-ply Shifts

    0.0 out of 5 stars 

    03 Jan 2017

    This tutorial shows how to use TexGen4SC to perform homogenization analysis of textile composites with arbitrary inter-ply shifts. A companion video is available on YouTube. TexGen4SC can be launched directly from https://cdmhub.org/tools/texgen4sc. A python script for the...

  2. The Challenges of Determining the Strength of Composites

    0.0 out of 5 stars 

    24 Nov 2020 | Contributor(s): Johnathan Goodsell

    Why are there such large differences in reported strengths of composites? Some of the reasons are the definition of strength, material variability, poor test methods, and subtle variations in carrying out the tests. But there are other important factors that affect strength that are not...

    13 Apr 2022 | Contributor(s): Johnathan Goodsell

    Permeability characterizes the capability of establishing a fluid flow through a porous medium. This lecture aims to present a summary on the state-of-the-art knowledge on permeability in LCM together with a discussion on open questions. The Story of Permeability in Liquid Composite Molding (LCM)...

  5. US-COMP: Next Generation of Composites Materials for Crewed Deep Space Missions

    0.0 out of 5 stars 

    15 Dec 2023 | Contributor(s): Johnathan Goodsell

    Current state-of-the-art composite materials are not light/strong enough for crewed missions to Mars and beyond. Structural components of deep space vehicles require lighter/stronger materials for fuel efficiency. The NASA Space Technologies Research Institute (STRI) for Ultra-Strong Composites...
