Hi,

I am learning Abaqus to model sandwich composite struture. If anyone has done that or has any tutorial for that, then please share.

Also I want to refer mathematical formulation of sandwich plates for dynamic stability analysis, please share.

 

Thanks,

applied spectrum wave on pipe288in ansys MECHANICAL ABDL13

Submitted by ganawa1988 on

DEAR MECHANICAL ENGINEERS

Iam relatively new ansys user and I want to apply spectrum wave (pierson moskowitz theory). I know to apply this load on ansys13 kwave 5 through 7 must be activated but when I was trying that only four theories are available,So how I can define kwave for example irregular wave (kwave =5) in ansys ABDL?

in advance thanks

ABAQUS - NON-LINEAR FOUNDATION

Submitted by jfonfria on

Dear collages,

 

I'm trying to develop a non-linear analysis. I want to model a foundation as a shell, and I want to consider the stiffness of the soil (but I have to define also that the stiffness in traction is = 0, and in compression is equal to the Winkler module). I want to develop this model in ABAQUS software. Could anyone help to me?

Thank you very much.

Regards,

Juan José

how to import subroutine file in abaqus software ?

Submitted by maneesht88 on

Sir,

 I am new to abaqus software. How can i import a subroutine file into abaqus software.while running a .inp file  added to job it asks for a sobroutine file.while editing the job file in general tab there is an option to include a subroutine file but while selecting a .f file to it. it asks for importing a .for or .obj file . what can i do now. I am studying about heat generations due to friction in contacts .the .inp file i imported into job is ufricxxy.inp and .f file is ufricxxy.f from help .please help me in solving these problems.

 

Failure of Bonded Glass

Submitted by dstrosch on

I work for an optics company and many of its products contain lenses that are bonded together with a very thin (~0.010mm) UV curing adhesive (Norland Adhesives NOA61 is the most common). Up until recently we have never had any issues with the strength of the bond. However we have recently had a particular design fail during a temperature cycle so I am tasked with looking at why, and how to keep it from happening in the future. The temperature range isn't too scary, -40 to +85C.

I need to calculate the height of hydraulic fracture using P3D and the width in the vertical direction. The width in the lateral direction is computed by displacement discontinuity method. These two widthes are totally different calculated by my coding. Please give me some advice.
