Fracture toughness analysis of composites
Hello,
I am doing my thesis on fracture toughness analysis ofcomposite material. Basically my work is to estimate stress intensity factorwhen reinforcement particle is very near to crack tip. I am using ANSYS for modeling and meshing.
I need help in selection of element type for crack tip,matrix material and reinforcement particle. And how to calculate KIc forcomposite material???
Thank you.
Is it a bug? can't manage displacement amplitude when applying it via function

Hello,
everyone!
I’m trying
to simulate different types of acoustic waves in linear anisotropic crystal in
order to measure their propagation speed (phase speed), and compare it with
experimental data.
Empirical observations of temperature
I have divided the old notes on temperature into three parts:
- Principle of the conservation of energy
- Empirical observations of temperature (this part)
- Energy and fundamental postulate
Our feeling of hotness comes from everyday experiences. These experiences indicate that many levels of hotness exist, and that all levels of hotness can be mapped to a real variable.

The notes and slides are attached. See related notes on thermodynamics.
Modelling a crack using ansys
How can i model a crack in a solid block(3D) in ansys. Do i need to use quater point elements at the crack tip or a general mesh will be sufficient.?
Carnot Cycle
Notes and slides for a course on engineering thermodynamics. I used the Dover edition of Carnot's book.
modeling of composite cylinder in abaqus
i am working on composite risers and it has inner steel liner and carbon epoxy layers ,where there are 19 layers with 88 and 0 degree orientation alternatively. plss help me in modeling it.
1) i have assumed nu12 =nu23 for transverse isotropy case. i needed engineering constants to give as material properties. am i right???
2)how to create local coordinate system and assign it material orintation.
