Hello,
I want to do transient analysis of piezoelectric actuator with varying preload acting on it in ANSYS. I really dont know how to proceed with. Can anybody suggest me how to proceed with some apdl examples.
Thank you

Load-bearing biological materials such as shell, mineralized tendon and bone exhibit 2-7 levels of structural hierarchy based on constituent materials (biominerals and proteins) of relatively poor mechanical properties. A key question that remains unanswered is what determines the number of hierarchical levels in these materials. Here we develop a quasi-self-similar hierarchical model to show that,
Unidirectional nanocomposite structures with parallel staggered platelet reinforcements are widely observed in natural biological materials. Our recent paper, published in J. Mech. Phys. Solids, is aimed at an investigation of the stiffness, strength, failure strain and energy storage capacity of a unidirectional nanocomposite with non-uniformly or randomly staggered platelet distribution.
Hello !
I have been reading quite a bit about decomposing deformation gradients into F=RU = vR where R = rigid rot'n, U = right stretch & v = left stretch. Since the principle stretch axes & basis vectors don't usually coincide, such stretches produce both stretch & shear as shown in animation at link below.
A singular value decomposition of U (or v) can be used to isolate the pure stretches. In my case, U is postive semi-definite so SVD given by eigenvalue decompostion as follows:
Hi all,
Currently, I am using ANSYS 12.1 for the fatigue crack propagation simulation for the edge crack & center crack plates. It is a mixed mode crack propagation.
Can anybody please tell me or guide me how to write the code in the ANSYS using APDL for automatic remeshing around the cracktip when crack propagates to the new position?
Thanks in advance. :)

how to model circular heat source and gaussian heat flux in ansys
how do i move circular heat source over a entire plate with time increments?
Thank you
