FROTRAN

I'm new in the computer simulation of adaptive bone remodeling (Bone will adapt to the loads it is placed under). And I know many research cases of numerical model were implemented as FROTRAN subrountines for the software package ABAQUS: the bone material properties will be updated by the subroutine.

I know FROTRAN is excellent at handling large data sets for scientific coumputing and requires less resources, but I haven't learned the FROTRAN.I wonder what else irreplacable advantages of FROTRAN in the bone remodeling?

Mechanics of Liquid and Solid Foams

This Special Issue of the International Journal of Solids and Structures includes sixteen articles presented at the international symposium: Mechanics of Liquid and Solid Foams. The symposium was organized under the auspices of the International Union of Theoretical and Applied Mechanics (http://www.iutam.net) and was held at the University of Texas at Austin in May 8-13, 2011. The papers deal with various aspects of mechanical behavior of cellular materials and foams in particular, and represent the state of the art in the field.

Can we give the output as the input for the new analysis.....

ABAQUS/CAE

Dear all,

I want to simulate the continuous forging operation in abaqus.

So after one forging operation, can i give the deformed shape as the input for the next cycle.

 

 

It would be kind of you to reply to me as soon as possible.

Thank You,

Can anybody recommend some papers/books that discuss how to caculate thermal induced warpage of lamianted composite materials? Paper/books with detial caculation/derivation process are preferred. Thanks a lot!

Excellent knowledge in nonlinear continuum mechanics, tensor calculus, numerical methods in solid mechanics and FORTRAN 90 is required.

 

If you are interested, please contact me, Dr. C. Broese, broese [at] mechanik.tu-darmstadt.de

 

A New Temperature-dependent Modulus Model of Glass/Epoxy Composite at Elevated Temperatures

Submitted by zhan-sheng guo on
research
high temperature; modulus model; composite

Temperature-dependent
modulus of glass fiber/epoxy composite laminates were studied at temperatures
ranging from room temperature up to 120℃. The storage modulus, loss
modulus, loss factor, and glass transition temperature of two layer-up composite
laminates were investigated by dynamic mechanic analysis (DMA). Static flexural
modulus was also measured by control force mode in DMA. A new and simple temperature-dependent
model both for the dynamic storage modulus and static flexural modulus was developed.

*NODE PRINT

Hello Experts,

 

I have written a uel subroutine where I have totally 12 degree of freedom. Among these 12 degree of freedom, 6 are standard abaqus degree of freedom (3 Displacements and 3 Rotations) and another 6 are User defined degree of freedom. 

I assign these these degree of freedom in following way.

*USER ELEMENT,TYPE =U9, NODES=9,PROPERTIES=24,coordinates=3

A first-order shear deformation finite element model for analysis of laminated composite and the equivalent FG plates

Submitted by M. Shaat on
research

In this paper, the first-order shear deformation plate (FSDT) model is exploited to investigate the mechanical behavior of laminated composite and functional graded plates. Three approaches are developed to transform the laminated composite plate, with stepped material properties, to an equivalent functionally graded (FG) plate with a continuous property function across the plate thickness. Such transformations are used to determine the details of a functional graded plate equivalent to the original laminated one. In addition it may provide an easy and efficient way to investigate the behavior of multilayer composite plates, with direct and less computational efforts. A comparative study has been developed to compare the effectiveness of the three proposed transformation procedures.
