Bring 3D Printing to the Mechanics of Composite Materials Course, ME446/646

The new lab modules instruct students (1) to design and fabricate carbon fiber reinforced composite beams and (2) to evaluate and test the strengths. The 3D printer used for this course is capable of printing continuous fiber,  Kevlar, and fiberglass and fabricating parts with a high strength-to-weight ratio. Printing of well-known reinforced structures widely used in aerospace and construction provides an opportunity to appreciate the knowledge delivered in textbooks. Design of fiber reinforcement patterns creates both anisotropic and quasi-isotropic ply constructions and results in a wide variety of mechanical performance. (Course offered in fall semesters.)

Create A Computer-Lab-Based Finite Element Analysis Course, ME457

This course presents approaches to computational modeling and simulation of the mechanical response of structures subjected to static, dynamic and thermal loads. The emphasis is on 2D/3D linear and nonlinear problems in mechanics. The course objectives are (1) to develop abilities to solve problems in solid and structural mechanics using commercial finite element software, ANSYS, and (2) to demonstrate an appreciation for the power of the finite element method and the limitations to the methodology. Students have access to ANSYS Workbench in the Engineering Computing Center and the Mechanical Engineering Computer Lab at UNR.

Topics cover: introduction to finite element, ANSYS Workbench project schematic, work flow, design modeler, mesh considerations, ANSYS mechanical, engineering data, static structural analysis, 3D solid elements, 2D analysis (plane stress, plane strain, axisymmetric problems), surface model and shell elements, line model and beam elements, multiple-body part, prestressed modal analysis, harmonic response, spectrum response, thermal (steady-state and transient) analysis, eigenvalue buckling, and contact. (Course offered in spring semesters.)

Incorporate the Mechanics of Architecture into ME751, Computational Structural Analysis

This course presents finite element fundamentals and advanced topics (e.g., post-buckling and thermal-mechanical coupling) in mechanics of materials and structures. Students combine theoretical and computational methods to gain deeper insight into the non-linear behavior of materials and structures. Students design their own projects to explore how material and geometric non-linearities influence deformation and mechanical instability in architected materials and structures. (Course offered in fall semesters.)
