Ls Dyna R12 Manual
Selina Basua
This report documents a concrete material model that has been implemented into the dynamic finite element code, LS-DYNA, beginning with version 971. This model is in keyword format as MAT_CSCM for Continuous Surface Cap Model. This material model was developed to predict the dynamic performance-both elastic deformation and failure-of concrete used in roadside safety structures when involved in a collision with a motor vehicle. An example of a roadside safety structure is a concrete safety barrier that divides opposing lanes of traffic on a roadway. Default input parameters for concrete are stored in the model and can be accessed for use. This material model only replicates the concrete aggregate. Appropriate reinforcement bars or rods must be included in the structure model separately.
The Users Manual for LS-DYNA Concrete Material Model 159 is the first of two reports that completely document this material model. This report documents the theoretical basis, the required input format, and includes limited hypothetical problems for the user. The second report, Evaluation of LS-DYNA Concrete Material Model 159 (FHWA-HRT-05-063), documents the testing performed to document the model's performance and accuracy of results.
This report will be of interest to research engineers who are associated with the evaluation and crashworthy performance of roadside safety structures, particularly engineers responsible for predicting the crash response of such structures when using the finite element code, LS-DYNA.
An elasto-plastic damage model with rate effects was developed for concrete and implemented into LS-DYNA, a commercially available finite element code. This manual documents the theory of the concrete material model, describes the required input format, and includes example problems for use as a learning tool. A default material property input option is provided for normal strength concrete. The model was developed for roadside safety applications, such as concrete bridge rails and portable barriers impacted by vehicles, but it should also be applicable to other dynamic applications.

I have spoken previously here about the merits of maintaining a dual-automated-manual calendar in Dynalist (rather than e.g. a google calendar). A dual manual-time-stamp calendar in Dynalist (and a crucial macro)
To generate a consecutive list of equal numbers that advance by one after a certain repetition (e.g. for week numbering, which can be really helpful for weekly reviews), you can use this little excel formula trick:
This document contains a table of contents for a motorcycle service manual. The table of contents lists 12 chapters that cover general information, troubleshooting, maintenance, the engine, clutch, transmission, fuel system, electrical system, wheels/tires, front suspension/steering, rear suspension, and brakes. It also lists supplemental sections on 1996-1998 service information, an index, and wiring diagrams.Read less
I've been using a digital version of the 2013 Dyna Manual for my 2014 Street Bob for the past year, because I've also been unable to find a digital 2014 one. I haven't come across anything in the manual so far that doesn't match my 2014 bike.

Introduction and objectives: Challenging percutaneous renal punctures to gain access to the kidney requiring guidance by cross-sectional imaging. To test the feasibility of robotic-assisted CT-guided punctures (RP) and compare them with manual laser-guided punctures (MP) with Uro Dyna-CT (Siemens Healthcare Solutions, Erlangen, Germany).
Material and methods: The silicon kidney phantom contained target lesions of three sizes. RP were performed using a robotic assistance system (guidoo, BEC GmbH, Pfullingen, Germany) with a robotic arm (LBR med R800, KUKA AG, Augsburg, Germany) and a navigation software with a cone-beam-CT Artis zeego (Siemens Healthcare GmbH, Erlangen, Germany). MP were performed using the syngo iGuide Uro-Dyna Artis Zee Ceiling CT (Siemens Healthcare Solutions). Three urologists with varying experience performed 20 punctures each. Success rate, puncture accuracy, puncture planning time (PPT), and needle placement time (NPT) were measured and compared with ANOVA and Chi-Square Test.
Deprecated since version 4.0: This brush engine has been removed in 4.0. This engine mostly had smoothing results that the dyna brush tool has in the toolbox. The stabilizer settings can also give you further smoothing options from the tool options.
