hai, im haidar (undergraduate-civil engineering from Malaysia)

Kindly please help me, 

currently im working on my thesis which majorly focused on the dynamic analysis of masonry (Concrete Masonry Unit) multistorey building structure,

presently, im modelling the 3 story building (including ground floor) of masonry building with block size of (200x400mm) including 10mm thickness of mortar joint

(macro-modelling) using the ABAQUS program. However, im facing few issues and confusion regarding on masonry modelling:

Hi every one

I try to analysis my Model at Abaqus. I want to use continume shell model to create the composite layer. The model shape is so complex and I can not use Hex meshing. Abaqus just meshing the model as Tetra element. And my problem is abaqus do not accept tetra az composite layer at element type. I try to daturm the model very smal part until may be can define hex element but its not work. There is any way I can use tetra meshing for continume shell.  

   Hello everyone I'm new here, Hope you can help me!

I was looking for an elastic material and I found a material called Spandex or Lycra(its trade name) I tried to find its mechanical properties on internet, but could not find specific calculation such as its Yielding stress and its modulus of elastisity(E), the most important thing i need is to find the maximum force or stress that it can stand.

Thank you.

Hi,

I have done compression test for concrete cube using Concrete damaged plasticity model. I assigned BC in Reference point which I coupled with a surf of the cube.

I have got stress-strain curve that looks nice, but Peak strength is 2-3 times higher than it should be.

Ia have uploaded pic of force-displacement.

Can anybody help me?

Thanks

Trying to model a crossply square plate with a sinusoidal temperature loading (uniform along the thickness). I am trying to match the results by Kant et al 2008 and Rohwer et al 2001. I am modeling the compoosite as a 3-D solid elements (making a part and dividing into 4 layers). I always obtain transverse shear stress on the 90 degree layer at 0,b/2,z to be zero.  My results match with that of the paper when I have a single layer of orthotropic material but they dont match when I have 4 layers of equal thickness and an aspect ratio of 5 (length/thickness).

I am doing my research in nonlinear vibration of beams. In that research, I have to derive the shape function for different end conditions of the beam. Regarding this,I need some ideas. Are there books I can reference?

Regarding my research work, I need to know about hermite cubics in Fem. Can any one suggest a book regarding this?

Hi ,

I am doing phd in nonlinear vibration. Regarding my thesis, I want to refer the following book

"Analytical and numerical methods for vibration analysis" by "Jong-Shyong"

Since the cost of this book is very costly, I am not able to afford this book. I am ready to buy the used copy of this book also.

Can anyone have used copy of this book?

If anyone have, plz provide the photocopy of that book.

If anyone knows, free download copy of the book, plz let me know
