    This creative project serves to explore the fields of choreography, lighting and music design, and virtual reality technology to create a performance piece. There is a growing surge of advances in virtual reality technology, and in order to keep the field of dance innovative and the discussion between the worlds of dance and technology relevant, we are interested in merging the two in a collaborative work. It is important to continue to present dance to audiences using different means to help achieve an experience for the audience and explore creative options in our own choreography. The overall goal of this research is to create an interesting modern dance performance that incorporates virtual reality technology. Our end result will be accomplished by dividing the work into three separate parts. Each team member will then focus on their area of the project. The first area is the dance choreography which will be entirely in a modern dance vernacular. The second aspect is the lighting and music design. The music will be chosen to set the mood of the piece, and the lighting will have to be enough to light the dancer, yet not over power the projections on the screen. The third aspect is the virtual reality aspect. The technology has been designed by the visualization department in collaboration with the dancers. The combination of these three aspects will form a performance piece that will be presented to audiences of various backgrounds.

    Finite element simulation of magnetohydrodynamic convective nanofluid slip flow in porous media with nonlinear radiation

    A numerical investigation of two dimensional steady state laminar boundary layer flow of a viscous electrically-conducting nanofluid in the vicinity of a stretching ∕ shrinking porous flat plate located in a Darcian porous medium is performed. The nonlinear Rosseland radiation effect is taken into account. Velocity slip and thermal slip at the boundary as well as the newly developed zero mass flux boundary conditions are also implemented to achieve physically applicable results. The governing transport equations are reduced to a system of nonlinear ordinary differential equations using appropriate similarity transformations and these are then solved numerically using a variational finite element method (FEM). The influence of the governing parameters (Darcy number, magnetic field, velocity and thermal slip, temperature ratio, transpiration, Brownian motion, thermophoresis, Lewis number and Reynolds number) on the dimensionless velocity, temperature, nanoparticle volume fraction as well as on the skin friction, the heat transfer rates and the mass transfer rates are examined and illustrated in detail. The FEM code is validated with earlier studies for non-magnetic non-slip flow demonstrating close correlation. The present study is relevant to high-temperature nano-materials processing operations

    Additive Manufacturing of Composite Polymers: Thermomechanical FEA and Experimental Study

    No full text
    This study presents a comprehensive approach for simulating the additive manufacturing process of semi-crystalline composite polymers using Fused Deposition Modeling (FDM). By combining thermomechanical Finite Element Analysis (FEA) with experimental validation, our main objective is to comprehend and model the complex behaviors of 50 wt.% carbon fiber-reinforced Polyphenylene Sulfide (CF PPS) during FDM printing. The simulations of the FDM process encompass various theoretical aspects, including heat transfer, orthotropic thermal properties, thermal dissipation mechanisms, polymer crystallization, anisotropic viscoelasticity, and material shrinkage. We utilize Abaqus user subroutines such as UMATHT for thermal orthotropic constitutive behavior, UEPACTIVATIONVOL for progressive activation of elements, and ORIENT for material orientation. Mechanical behavior is characterized using a Maxwell model for viscoelastic materials, incorporating a dual non-isothermal crystallization kinetics model within the UMAT subroutine. Our approach is validated by comparing nodal temperature distributions obtained from both the Abaqus built-in AM Modeler and our user subroutines, showing close agreement and demonstrating the effectiveness of our simulation methods. Experimental verification further confirms the accuracy of our simulation techniques. The mechanical analysis investigates residual stresses and distortions, with particular emphasis on the critical transverse in-plane stress component. This study offers valuable insights into accurately simulating thermomechanical behaviors in additive manufacturing of composite polymers
