Tissue strain-rate independence

I have two basic questions for the experts in the soft tissue biomechanics community.
a) I am interested in the biomechanics of a specific tendon in a specific high-speed deformation. How plausible is it for me to assume strain-rate independence, and therefore, the existence of a strain energy function? In other words, how accurate is the assumption of pseudoelasticity for tendons under high strain-rate? I feel comfortable with the assumption (evidence would help a lot, however) for tissues such as mesentery, skin and, I guess, even muscle.

Building and Environment Special Issue on the Implications of a Changing Climate for Buildings
Edited by Pieter de Wilde and David Coley, this special issue of Building and Environment deals with the implications of a changing climate for buildings. Climate change is considered to be one of the main challenges facing humankind in the 21st century, with serious and global consequences for the environment, human health, and the economy.
Seeking a PhD researcher at Univerisity of Arkansas at Little Rock
The group of Advanced Materials and Dynamics
Lab at the University of Arkansas at Little Rock is seeking one highly
motivated candidate for Ph.D. positions. The appointment is starting on January
2013 or August 2013. The research topics involve dynamic modeling, elastic wave
propagation, structural health monitoring, experimental design and analysis of
the multifunctional elastic/acoustic metamaterials. A M.S. or equivalent degree
in solid mechanics, mechanical engineering, wave propagation, or material
science is needed. Talented applicants with a B.S. degree in the above field
Computational models for mechanics of morphogenesis
In the developing embryo, tissues differentiate, deform, and move in an
orchestrated manner to generate various biological shapes driven by the complex
interplay between genetic, epigenetic, and environmental factors. Mechanics
plays a key role in regulating and controlling morphogenesis, and quantitative
models help us understand how various mechanical forces combine to shape the
embryo. Models allow for the quantitative, unbiased testing of physical
mechanisms, and when used appropriately, can motivate new
experimentaldirections. This knowledge benefits biomedical researchers who aim
to prevent and treat congenital malformations, as well as engineers working to

Hi,
Is there a place I can find explained examples or tutorials on how to model user defined creep in ANSYS?
I need to follow the creep law __> effective creep strain (e at time t) = S. T. e^(-H)
S=(a0)^t.(sigma)^(a1) ; T = t^(a2)+(a3).t^(a4)+(a5)t^(a6) ; H = (a7)/[(theta)+273.16]
a0 to a7 are material constants.
I have the experimental data and tried to fit the curve in Ansys to obtain the material constants.
