The mechanical performance of H-shaped NCF adhesively bonded joints

Submitted by Konstantinos I… on
research

Adhesive bonding is contemplated as an alternative method to mechanical fastening for joining composite aerostructures.

Ongoing research in this area is focused on the development of new bonding techniques and joining elements. In this

article, the mechanical performance of the novel noncrimp fabric (NCF) H-shaped adhesively bonded joints subjected to

tension, shear and four-point bending loading conditions was investigated by both experimental tests and numerical

How to understand the shear modulus of polymers

Hi everybody,

I have a question about the shear modulus of polymers. As we know, the general engineering polymers （rubbers） are highly extensible and elastic. The shear modulus，G， for the polymers subjected to the small-strain conditions, can be defined by G=NkT, where N is the number of network chains, k is Boltzmann's constant and T is temperature in Kelvins.

python scripting

Hello,

 I am using python script to automate a repeatative task. During this I am faceing problem. Please help.

I have created a sketch by

 mysketch= mdb.Model(name='Cantilever') .ConstrainedSketch(name='beam', sheetSize=200.0)

 mysketch.rectangle(point1=(0,0), point2=(100,10))

I want to take underlined numbers as an input from user for that i have defined variavles as l and w of cantilever. When I use this  

 mysketch.rectangle(point1=(0,0), point2=(l,w))

abaqus gives error during compilation.

question about "Extended Dracker Prager plasticity model"

Submitted by Gamal on

Hi my friends,

i am using Dracker Prager Plasticity model in abaqus 6.6, i am working on rock sample, this rock sample shows strain softening behavior not strain hardening, but you know that Drucker Prager can simulate both hardening and softening.

i have the stress-srain diagram from the laboratory test. 

 my shear criterion is linear, i choosed from Suboption   Drucker Prager Hardening.
