  2. Simulation of prepreg platelet compression molding: Method and orientation validation

    18 Jul 2019 | Contributor(s): Sergey Kravchenko

    Prepreg platelet molding compounds (PPMCs) offer improved performance potential as compared to short-fiber composites and increased geometrical complexity as compared to continuous fiber composites. The increased adoption of PPMCs in automotive and aerospace applications necessitates the...

  3. Fiber orientation measurement from mesoscale CT scans of prepreg platelet molded composites

    18 Jul 2019 | Contributor(s): Sergey Kravchenko

    X-ray computed tomography (CT) analysis is used to measure the heterogeneous fiber orientation fields in a 20 cm3 composite bracket made from prepreg platelet-based molding compound (PPMC). The as-molded mesostructure of the complete geometry is captured using...

  4. Tensile Properties of a Stochastic Prepreg Platelet Molded Composite

    17 Jul 2019 | Contributor(s): Sergey Kravchenko, Drew Sommer, Benjamin Denos, Tony Favaloro, Byron Pipes, William Avery, Clark Tow

    The stochastic prepreg platelet molded composite (PPMC) occurs when the orientation and arrangement disorder of platelets are determined by the uncontrolled molding conditions. The understanding of composite structure-property relationship is essential for the engineering applications of PPMCs....

  5. Structure-property relationship for a prepreg platelet molded composite with engineered meso-morphology

    17 Jul 2019 | Contributor(s): Sergey Kravchenko, Drew Sommer, Benjamin Denos, William Avery, Byron Pipes

    The objective of this work was to develop a finite-element based computational model to investigate the complex three-dimensional load transfer from the known meso-structure of a prepreg platelet molded composite (PPMC) system with a layered planar morphology and...

  6. Uniaxial strength of a composite array of overlaid and aligned prepreg platelets

    17 Jul 2019 | Contributor(s): Sergey Kravchenko, Drew Sommer, Byron Pipes

    The tensile strength of a discontinuous composite system consisting of aligned, unidirectional prepreg platelets is predicted by performing progressive damage analyses in a periodic representative volume element. Interlaminar and in-plane damage mechanisms are combined to...

  7. Structure-property relationship for a prepreg platelet molded composite with engineered meso-morphology

    17 Jul 2019 | Contributor(s): Sergey Kravchenko, Drew Sommer, Benjamin Denos, William Avery, Byron Pipes

    The objective of this work was to develop a finite-element based computational model to investigate the complex three-dimensional load transfer from the known meso-structure of a prepreg platelet molded composite (PPMC) system with a layered planar morphology and...

  8. Physics-informed artificial neural network approach for axial compression buckling analysis of thin-walled cylinder

    20 Jun 2019 | Contributor(s): Fei Tao

    Buckling leads the failure of thin-walled cylinders under axial compression. Due to the manufacturing imperfection, a significant variation was observed between experimental and theoretical buckling load. The current design criteria use knockdown factor to estimate the buckling of thin-walled...

  9. MSC.Patran/Nastran-SwiftComp GUI

    01 Apr 2019 | Contributor(s): Xin Liu, Wenbin Yu

    A graphical user interface (GUI) has been developed to integrate SwiftComp into MSC.Patran/Nastran for constitutive modeling and providing the automated conversion of the MSG plate and beam stiffness matrix into MSC.Nastran shell and beam element properties and materials. In order to reduce...
