ANSYS claasic

Hello ANSYS  users,

 

I am having hard time ANSYS's documentation for fatigue analysis in claasic environment. Tutorials available on internet talk bat ansys workbench only. Has anyone done fatigue analysis in ANSYS claasic? If yes, is there any source for tutorials ?

 

Thanks,

 

Say hello to everybody

Hello, I'm a new comer here although I registrated a user name about 48 weeks ago. I have learned a lot for all of you, from micro mechanism disucction to macro phenomena explanation. My major research interests include: impact dynamics, high-performance of energy absorption material, vehicle safety and accident reconstruction. Anybody with the same/similar interests as mine, please discusscus any topics raised during the research. I hope we all can be good friends.

Sincerely,

Jun 

Modeling Reinforced Concrete Element in Abaqus Standard

Submitted by looyong on

hello everyone,

I am trying to model a concrete element subjected to static load using Abaqus Standard. For concrete, I am using Concrete Damaged Plasticity and beam elements for my reinforcement. I am embedding my reinforcement into the concrete (host elements).

Since I started, I faced several issues. They are overconstraint, numerical singularity and negative eigen values. I managed to resolve both of them. However, the behavior from my model is nowhere near the experimental data that I have. It seems that the model is excessively stiff.

Bridging the gap with a "stepping stone" for more solar energy

Submitted by Zhenyu Zhang on
research

Converting the abundant energy from the sun into a form convenient for human use has been a long standing dream for sustainable generation of environmentally clean energy.  With the seminal discovery of water splitting by Fujishima and Honda in the early 1970s [1], titanium dioxide (TiO2), an inexpensive white pigment widely used in our daily life, emerged as the premier photocatalysts for enabling solar energy utilization. However, because of its wide intrinsic band gap, TiO2 can absorb only ultraviolet light. This results in less than 1% efficiency for solar energy conversion. Reducing the band gap of TiO2 is the main avenue for boosting the conversion efficiency. In a recent paper to appear in Phys Rev. Lett. [2], Zhu et

Effective strain range

HI everyone

 

I am doing research using Sih's strain energy density concept for predicting  fatigue failure in asphalt pavements.  I am pretty new in this area and got stuck while reading some papers. Anybody has some idea how to predict the effective strain range near the crack tip. 

 

ΔE= A/Rj∫ΔEeff dr

and 

 how to get the constant A and β.

Green Tribology

tribology

Tribology is defined as the science and technology of interacting surfaces in relative motion, which involves friction, wear and lubrication.

The term “tribology” was introduced in the 1960s by Prof. Peter Jost.  In the consequent decades, various aspects of interacting surfaces in relative motion have been the focus of tribology, including, for example, the tribology of automotive applications, microelectromechanical systems, magnetic storage devices, adhesive contact, micro/nanotribology, biotribology.
