I have a doubt regarding the Hyperelastic and Viscoelastic material modelling in ANSYS using Mooney-Rivlin material constants.
ANSYS theory manual says that for large deformation and large strains, the material modelling (i.e. constitutive behaviour) is same for hyperelastic and viscoelastic. Is it so?
Generally, Mooney-Rivlin material constants are used to model Hyperelastic behaviour (rubber-like materials).
Recently, I have a question on the plasticity.As the plastic materials undergo the loading and unloading process. we can find the energy dissipation from the stress and strain relation curve. Then, my question is that the energy dissipation is generated during the loading process or unloading process?Thank you very much.
The application of mechanics to biology
– biomechanics – bears great challenges due to the intricacy of living things.
Their dynamism, along with the complexity of their mechanical response (which
in itself involves complex chemical, electrical, and thermal phenomena) makes
it very difficult to correlate empirical data with theoretical models. This
difficulty elevates the importance of useful biomechanical theories compared to
other fields of engineering. Despite inherent imperfections of all theories, a
Given the complexity of present and
future global challenges, it is the university´s social responsibility
to contribute to society by understanding the full extent of its needs
and current and future problems, and to prepare it to deal with them
effectively and efficiently (CMES, 2009)1. In this sense, due to its
ability to take the lead in matters of knowledge creation, promotion and
dissemination, the university becomes the ultimate guidance governments
possess in their quest to find solutions to inequality and exclusion.
As many othes, I find myself in the position that my funding agency mandates some form of parallel publishing (or preferably OpenAccess) (as well as an Open Access policy from my university itself).
I've been reading through what author rights i retain with different publishers, and among the big ones very little rights are retained.
Elsevier allows preprints to be published only if it is voluntary. That is, they intentionally prohibit mandated parallel publishing to protect their profit.
Wiley had different rights with different journals, but my first hand choice simply didn't allow parallel publishing of any kind ever.
As a journal editor, I am often surprised by some of the suggestions authors make for potential reviewers. In some cases the suggestions are not very good, and on occasion authors do not suggest reviewers at all. Some authors will even state explicitly that they cannot think of any reviewers, which is really surprising.
Upto what limit is hooke's law really obeyed ? some books say that hooke's law is obeyed up to the proportional limit, while some other books say that hooke's law is upto the elastic limit ? what is the correct answer?
I am not clear about two concepts: thermodynamics equilibrium state and steady state. It's easy to conceive of the following different two osmosis processes regarding thermodynamics equilibrium state and steady state, respecitvely.
hi everyone ,
im finding the subject of my thesis(in master science) i will be glad if anyone offer me the subject with satisfactory future , my tendency is applyed mechanic in stress !
please explain about the future job,
thank you
