Fracture Toughness of Stitched Composites

Submitted by DevrimG on

 

Dear Colleagues,

I am studying on Interlaminar Properties of 3D Textile Composites. Especially I am focusing on Fracture Toughness of Stitched Composites. Anyone can suggest useful Journal Papers about Stitched Composites and/or Mode I- Mode II Testing for Literature review?

Kind Regards,

Devrim Goktas 

 

 

Adventures in 9-space

Submitted by Robert G de Boer on

The three by three matrix is a workhorse for mechanicians, yet the study of this tool is seldom addressed mathematically. One reason is that the space of such matrices is nine-dimensional, quite beyond diagrams and  vision. The advantage of a mathematical investigation of the matrix space is clear in the study of two by two real matricies where rotations, shears, and squeezes correspond to area-preserving transformations of the plane. For transformations of space that preserve volume there is a much richer variety of phenomena that may correspond to mechanical events.

How to simulate boundary conditions and apply uniformly distributed load to shell element when I do nonlinear analysis of I-BEAM

Submitted by speedeagle on

Hi, everyone:

I am using ABAQUS to do my final dissertation:nonlinear analysis of steel members.

When I simulated the beam with shell element, first I define reference points at both end of the beam and assign 'RIGID BODY/PIN OR TIE' to  nodes at the edge,after that I applied bending moments and boundary conditions to both reference points.  But after I finished the buckling analysis, the result is not reasonable,the eigen value is about two times the the value I expected.

In situ nanocompression testing of irradiated copper

Submitted by Daniel Kiener on

Dear colleagues,

we recently published a paper on measuring bulk properties of irradiated copper from nanoscale samples:

Hope you find this interesting!

Variables definition in Abaqus

Submitted by Laurianne on

Hi,

I am working on a 3D contact problem where a spherical part is pressed against another spherical surface. I was wondering what variables may be interesting to study for this problem. I decided to look at the contact area CAREA, the contact pressure CPRESS and the stress S but I am not able to find how Abaqus defines and calculates these variables, does anyone know?



Thanks

energy balance of surface-based cohesive of composite under impact in Absqus 6-10

Submitted by moustachiio on

Hi there! I am really new to Abaqus and I need to model a composite
laminated crash cone under impact to a flat solid wall (analytical
surface is used). I modelled a cone with a layers of conventional shell
elements with hashin failure criteria and surface-based cohesive
behaviour as interaction between layers representing the interface of
composite laminates. The model runs successfully but once I checked the
energy balance, the damage dissipation energy from the cohesive, it
turned out to be NEGATIVE (I think this is wrong).
