A material model driver for DYNA3D
This report describes a material model driver which has recently been implemented in the DYNA3D code. The material model driver allows plotting of the constitutive response predicted by a material model under a given load path. This capability is particularly useful when fitting complex material models to experimental data. The plotting capability of the material model driver facilitates comparison of the simulated material stress-strain behavior with actual material test results. 1 ref., 6 figs., 4 tabs

DYNA3D example problem manual
This manual describes in detail the solution of ten example problems using the explicit nonlinear finite element code DYNA3D. The sample problems include solid, shell, and beam element types, and a variety of linear and nonlinear material models. For each example, there is first an engineering description of the physical problem to be studied. Next, the analytical techniques incorporated in the model are discussed and key features of DYNA3D are highlighted. INGRID commands used to generate the mesh are listed, and sample plots from the DYNA3D analysis are given. Finally, there is a description of the TAURUS post-processing commands used to generate the plots of the solution. This set of example problems is useful in verifying the installation of DYNA3D on a new computer system. In addition, these documented analyses illustrate the application of DYNA3D to a variety of engineering problems, and thus this manual should be helpful to new analysts getting started with DYNA3D. 7 refs., 56 figs., 9 tabs
Layered Blast Capacity Analysis of FRP Retrofitted RC Member
Fibre reinforced polymer (FRP) retrofitting of RC structures against blast loading is an emerging research area of major significance. Currently, several guidelines are available for the FRP retrofitting of RC structures against monotonic and seismic loads. However, no advice is provided from these guidelines for the retrofit RC structures against blast loading. This paper formulates a layered model that allows for both FRP strengthening and the consideration of strain rate effects on the blast resistant capacity of flexural structural members. The layered model is incorporated into a single degree of freedom model for dynamic analyses and it is validated with blast tests. The validated model is then used in a parametric study which investigates the changes in strength, ductility and energy absorption capacities of flexural FRP strengthened members under blast loads. It is found that the capacity of a flexural member to resist a blast load can be increased greatly with the use of compressive face plating with the ductility of the flexural member being the key factor.Chengqing Wu, Deric John Oehlers and Ian Da
