Good study material about fracture mechanics

Submitted by Shantanu S. Mulay on

Dear all,

Can anyone suggest a good study material (lecture notes/videos/books) about the fundamentals of fracture mechanics (specially cohesive law for orthotropic materials)?

I checked few books, but they are not very clear. So, I want to go for something that is already tested.

Thanks in advance for the help. 

Shantanu.

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.

Computational models for mechanics of morphogenesis

Submitted by zichen on

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

Question about the meshfree analysis when two types of materials coexist in the background cell

Submitted by bahamute on

Hi, everyone!

I will employ the meshfree method in order to analyze the composite model including the spherical filler and matrix.

However, if the background cells are regular reluctantly, there will be background cells where two types of materials coexist.

In this case, I don't know how to calculate the integral form, K=int_V B'CB dV, numerically.
