Energy Security, Global Warming and Engineering
One research report (Energy Security.pdf) is attached with this post. It is about how we can use engineering to slove energy and global warming problem.
Help needed in defining Gap Elements in Abaqus
Hi
I want to know how we can define a Gap Element In ABAQUS
I am doing a research about simulating a delaminated plate by FE Gap Elements
Please Help
Thanks an advance
How to analyze a short arc using elastic mechanics?
Hello, everyone, I am a freshman here, and I am very happy to find this place as a mechanics student. Hope to communicate with everyone here.
I am studying a hole effected by surface effect. I want to know how to analyze the stress on a short arc.
If you know about it, and you are willing to share it with me, I will be very grateful about it!

Basic Concepts of Numerical Methods
I am looking for basic concepts of numerical methods. I have also an important question: Why numerical methods?
I would be grateful if you could give me a good answer.
Buckling due to Welding Stresses
I am modeling weld induced residual stresses in circumferentially welded thin-walled cylinders. Any one guide me how to conduct buckling analysis due to weld induced residual stresses in ANSYS.
The Change of Microstructure at low temperature

Recently, we do some work about the dynamic strain aging. In order to investigate the function of solute clouds and precipitates in DSA, we do some experiments. The solution treated LY12 alloys are tested on MTS at low temperature (173K), and the Portevin-Le Chatelier phenomenon disappeared as we expected. But, we need more information about the change of microstructure under the low temperature, what is more the micro-optical observation should be finished in a very short time when we consider the effect of natural aging. Obviously the TEM can not meet our needs.
Equilibrium and stability of dielectric elastomer membranes undergoing inhomogeneous deformation
Dielectric elastomers are capable of large deformation subject to an electric voltage, and are promising for uses as actuators, sensors and generators. Because of large deformation, nonlinear equations of state, and diverse modes of failure, modeling the process of electromechanical transduction has been challenging. This paper studies a membrane of a dielectric elastomer deformed into an out-of-plane, axisymmetric shape, a configuration used in a family of commercial devices known as the Universal Muscle Actuators.
Recommending a book on FSI with recent discussion on Immersed Boundary/Continuum Methods
I am writing to recommend my book “Fundamentals of Fluid-Solid Interactions-Analytical and Computational Approaches” recently published by Elsevier Science. The book is available in amazon.com webpage or Elsevier Science webpage. The following is
