The CAE - Finite Elements competitive market . FE market: linear and non linear: . MSC suite: Nastran and MARC . Ansys . Abaqus . Nei Nastran – NX Nastran . LS Dyna . Cosmos . ALGOR . Radioss . Pamcrash 1 - ASD Competence Center - 2011 Linear Market . 2 categories: . High end software: SAMCEF, ANSYS, Nastran (all of them) . No big difference between them (NL contact in SAMCEF maybe?) . Branding, GUI and existing models are the differentiators . Low end: Cosmos, ALGOR, Catia GPS . Sold as add-on to CAD packages . Limited features available . Mesh “across the CAD” and push a few buttons to get results . Used mostly when rough results are OK . Cost ~5k€ 2 - ASD Competence Center - 2011 Non Linear market . Implicit: MSC Marc, Abaqus, ANSYS, SAMCEF Mecano, Recurdyn & Dafool . Abaqus and MSC Marc are more dedicated to pure structural analysis (include very large defos, metal forming for example) . SAMCEF Mecano is better suited for Flexible Dynamics Analyses . SAMCEF Mecano best suited for slow dynamics (10-> 500 Hz, > 10s simulation time) . Explicit: LS Dyna, Abaqus, Radioss . Suited for fast dynamic analyses (impact, crash, blasts,…) . Limited simulation time due to very small time steps (1e-6s) . Still popular to model slow dynamics with Explicit, even of not a good idea 3 - ASD Competence Center - 2011 MSC offer . Is the sum of purchases, very little internal developments . Nastran is made of many modules: SOL XXX . Comes with the Masterkey license concept: tokens can be used to launch any solver . Used to be very heterogeneous. Nastran, Marc and Adams came with no compatibility and different GUI. Better now with MD Patran/Nastran? Adams still out. Nastran = the standard for linear analysis in aeronautics. Impossible to change that! . MSC was bought by equity firm Symphony in 2009 and relaunched a lot of products developments since then (MD Patran, Adams 2010…) 4 - ASD Competence Center - 2011 ANSYS offer . The most homogeneous and complete competitor . Strong hold on energy market, less present in aero . Most products developed in-house . Focus on multiphysics, especially FSI. Own a couple of CFD codes (Fluent, CFX) . Mechanical offer contains few modules: only ANSYS Structural and ANSYS Mechanical . Have a FMBD solution but don’t advertise it (yet) too much . ANSYS Workbench = important player on the GUI market, even for non ANSYS users 5 - ASD Competence Center - 2011 Abaqus offer . Abaqus purchased by Dassault in 2005. Became the core of Simulia, the simulation platform of Dassault . Standard solution for structural non linear analyses . Offer both Implicit and Explicit . No linear package => always comes on top of something else 6 - ASD Competence Center - 2011 Recurdyn and Dafool . For Flexible MBS, come with similar messages as SAMCEF Mecano: real FEA inside MBS . Are somewhat popular in Asia, not anywhere else . Harmed us a lot in Korea 5 years ago, but the bubble exploded 7 - ASD Competence Center - 2011 GUI market . SAMCEF Field . Patran : MSC GUIs; old fashioned but still very much used (old standard) . ANSYS Workbench: multiphysics oriented; includes workflows and model management on top of FEA GUI . Hypermesh: Most popular FEA GUI for mesh generation, driving +/- 50% of Nastran licenses. 8 - ASD Competence Center - 2011.

84Th Program
th 84 Shock and Vibration Symposium Atlanta | November 3-7, 2013 CONFERENCE PROGRAM 2 Introduction Welcome to Atlanta and the 84th Shock and Vibration Symposium! Since the first meeting in 1947, the Shock and Vibration Symposium has become the oldest continual forum dealing with the response of structures and materials to vibration and shock. The symposium was created as a mechanism for the exchange of information among government agencies concerned with design, analysis, and testing. It now provides a valuable opportunity for the technical community in government, private industry, and academia to meet and discuss research, practices, developments, and other issues of mutual interest. The symposium is presented by HI‐TEST Laboratories and The Shock and Vibration Exchange. Our special event sponsors are National Technical Systems, PCB Piezotronics, Team Corporation, and Weidlinger Associates. About the Host and Special Event Sponsors... At HI‐TEST, we work 24/7 to provide our customers with complete test program solutions, from pre‐test analysis to post‐test report generation. We have provided testing and evaluation services to government and industry since 1975. Today, HI‐TEST is a single‐source solution to your testing programs, offering numerical and analytical engineering tools and expertise alongside our world‐class testing capabilities. We offer complete test support with our reputable and experienced team of engineers, instrumentation technicians, craftsmen and support staff, including design, fabrica‐ tion and installation of test fixtures, as well as equipment repairs and modifications. In 2008, HI‐TEST created the Applied Technology (AT) Division allowing us to offer numerical and analytical expertise alongside our testing capabilities.
