I’m working on optical method for displacement measurement. and this is interesting to know more about application and development of these methods like ESPI , SHEAROGRAPHY anf HOLOGRAPHY . for example i face with a company that climb their product can give displacement and so strain field in many material and many geometry even in 3-D shapes!!
Hi everybody,
Is there any limits for using of LEFM? I have modelled a beam with a penetration.I have moved the holes vertically in the beam and obtained the stress intensities for each movements at the corners of the hole. Now the hole is closing the edge, stress intensities in mode I and II, suddenly change values (positive to negative and vice versa) what does this mean ?... Does it mean that I should limit my movements?,,,,
Thank you,

The Cardiovascular Biomechanics Lab in the Department of Mechanical Engineering at The University of Texas at San Antonio (UTSA) is seeking a highly motivated postdoctoral fellow to join our research team. The position is supported by a research grant from the NIH to study the mechanical stability and tortuosity of blood vessels. Qualifications include a doctoral degree in BME or ME in computational fluid mechanics, or computational biomechanics.

The book I recommend for reading is Fracture mechanics: fundamentals and applications, by T.L.Anderson, 3rd edition, 2005. I first saw this book on the top list of reading materials of Brown U. When I have it I found so pleasent to read through it. Here is the short-list of its content
Chapter 1: Introduction: History and overview
Chapter 2:Fundamental concepts: linear elastic fracture mechanics
Chapter 3: Elastic-plastic mechanics
Chapter 4: Dynamic and time-dependent fracture
Chapter 5: Material behavior: Fracture mechanics in metals
Hello,
I am trying to simulate crack propagation in ANSYS. I am stucked in Cohesive Zone meshing.
I have gone through all the posts posted here.
I have understood that CZ Meshing is done through command line ANSYS. Even I gave try for it but was unfortunate.
Hi evrey body,
Does anybody have an idea for solving torsion equation for trapezoidal bars? Or any references? For rectangular bars Timoshenko completely did it in in "Theory of Elasticity" pages 309-313, but I could not find any references for trapezoidal cross section.
Best Regards
