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.
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.
I have divided the old notes on temperature into three parts:
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.
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.?
Notes and slides for a course on engineering thermodynamics. I used the Dover edition of Carnot's book.
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.
Hi All
I'm a bioengineering PhD student, I just started reading on the finite elasticity theory and have a question regarding to the governing equation.
As I understand, Cauchy's first law of motion is the governing equation for finite elasticity. For steady-state (no acceleration), the equation is:
dσ/dx=F
