piezoelectric composite beam analysis using ABAQUS
Hi!! all
I am doing analysis of piezoelectric composite beam as 2-d problem. there are 5 layers. top layer is PZT-5A and bottom 4 layers are cross ply graphite-epoxy . beam is simply supported and load is udl pressure. plz tell me how to model this beam in ABAQUS.
Thanks u.
ASME 2008 Conference Track on Mechanics of Solids, Structures and Fluids
The ASME International Mechanical Engineering Congress (IMECE 2008) will be held on October 31 - November 6, 2008, in Boston, Massachusetts. http://www.asmeconferences.org/Congress08/. A wide range of mechanics-related symposia (topics) are being organized in Track 12 Mechanics of Solids, Structures and Fluids. The Executive Committee of the ASME Applied Mechanics Division (AMD) believes that this track will provide a good platform for mechanics-related presentations.
Fracture energy - Garwood method?
Anyone know the Garwood method which is used to determine the fracture energy of concrete (composite materials)?
Garwood method: with a load - load line displacement curve of an three point bending fracture test (or SENB), we have firstly:
J0=2U0/B(H-a0)
After, an iterative relation is used:
Jn=Jn-1(H-an)/(H-an-1)+2Un/B(H-an-1)
B,H : width and height of the beam respectively.
a : crack length
Material model of Kevar composite for Impact problem
I am looking for material model of Kevlar composite for Ballistic impact simulation. Presently i am using ANSYS. Can any body suggest material model for kevlar composite for fracture and penetration phenomina.
ON THE MECHANICS OF HELIX
Helix is a very interesting structure. There are many biopolymers that have a helical structure.
- How can someone model the helix in mechanics?
- How can the helix reinforce a rod?
- How does this structure reflect the mechanical properties of biopolymers?
Postdoctoral Position at Penn State University in Multiscale Computational Dynamics
We have an immediate opening in the Department of Engineering Science and Mechanics for a postdoctoral research associate in multiscale modeling and computational mechanics. The focus of this position is on the modeling, simulation, and analysis of the nonlinear evolution of coupled macro/microstructure in failure processes, with an emphasis toward structural health monitoring. Coupled-field models using continuum damage variables will be used to study the fundamental spatiotemporal features of damage evolution, particularly regarding the nature and origin of unpredictability in damage processes. The candidate must have a solid general background in theoretical mechanics and dynamics, and be familiar with nonlinear finite element analysis
Physics programmer position in Boston
The person in this position will be responsible for developing finite element-based soft tissue representations that supportreal-time interaction with surgical tools. The successful candidate should befamiliar with the extensive prior work in the field of surgical simulationincluding finite element formulations (both traditional nonlinear approaches aswell as various real-time approximations), real-time collision detection andresponse between rigid and deformable objects, multi-processor/coreimplementations, and integration with haptics devices.
