ESRD announces the release of StressCheck 7.1
Date posted: 5/3/2007

ESRD, a leader in finite element analysis (FEA) technology, today announced the release of StressCheck 7.1.  This release adds powerful new features in the areas of nonlinear analysis and rapid detail modeling of composite parts.  ESRD has implemented the incremental theory of plasticity to provide analysts the ability to simulate the residual stress field produced by multiple load-unload events.  This capability, funded by the Boeing Company, offers accurate solutions for cold working, interference-fit fasteners, and other fatigue life enhancements used in the aerospace industry.

ESRD continues to add more functionality to its already superior pre- and post-processing capabilities for laminated composites.  The new Automatic Lamination tool provides quantum improvements in efficiency in the time it takes to create detailed ‘ply-by-ply’ models representing composite structure.  This easy to use tool discretizes the parent mesh to create the individual plies in the laminate stack, maps the plies to the natural curvature of the part, and assigns material properties and ply orientation in a single step.

ESRD receives SBIR Phase I funding for FACIA related development from the US Navy
Date posted: 10/15/2004

ESRD announces receipt of a Phase I Small Business Innovative Research (SBIR) contract.  The overall objective of the project is to demonstrate the feasibility of incorporating the following features into a p-version FEA code, StressCheck®:
  1) Shell element and a transition element to connect a shell to a 3D solid element.
  2) Laminated orthotropic material properties that follow the general curvature of a shell or solid element.
  3) Contact element and a 3D fastener element that simulates clamp-up of the head and nut.

Upon completion of Phase I technical objectives, StressCheck will offer the features necessary to analyze cocured/cobonded composite joints and fastened assemblies that include one or more composite parts.  Combined with the current features of StressCheck, including the parametric Handbook and built-in quality control, analysts will have an accurate and efficient failure prediction tool for laminated composite structures utilizing SIFT methodology.

CAI announces the selection of StressCheck for analysis of bonded composite joints
Date posted: 5/01/1999

StressCheck is currently being enhanced at the direction and with the support of the Composites Affordability Initiative (CAI).  The CAI is a partnership of industry and government agencies (Boeing, Lockheed Martin, Northrop Grumman, the office of Naval Research, the JSF Program, and the Air Force Research Laboratory). The goal of CAI's enhancements to the StressCheck code is to make the design and analysis of composite joints more accurate and efficient through FEA methods.

What the CAI group said about StressCheck:
“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
