Problem physics- shallow truss element-Non linear FEM

Submitted by bruno-page on

I have got a shallow truss element-same as in Crisfield’s book.

I have a truss configuration as in the attached file (simple 1 member as in Crisfield as Bathe) . I have a load W = 42 units applied (the force causes compression in the member).I have used incremental approach wherein the laod is applied in 6 increments of 7 units each.

Hi! I want Subroutine umat for Hypoplasticity model,Sdvini and inp.file one-element(Fortran source) for ABAQUS.

Hi everybody

    At present, I am studying for master's degree for geotechnical engineering.  I am

interest in subroutine umat for ABAQUS very much. Especially, subroutine umat

drained and undrained condition.  I wish you, who has them or know a website to

download them. I wish you to send subroutine umat drained and undrained

Postdoctoral position at MIT on inverse problems in multiscale materials modeling

Submitted by demkowicz on

One postdoctoral position is currently available for individuals with a strong background in materials simulations—preferably atomistic methods—to develop approaches for solving inverse problems in multiscale materials modeling (i.e. determining what atomic-level structures and compositions yield desired macroscale properties, rather than predicting macroscale properties given atomic-level information). These methods will be applied to the design of radiation resistant nanocomposites in collaboration with an Energy Frontier Research Center (EFRC) at Los Alamos NL.

Finite elements based on shell theories

Hello,

 

Recently I faced two questions in course that I am attending:

 

1) Outline the salient features of different higher order shell theories.

 

2)Explain why some shell theories are not suitable as the basis of element formulation.

 

3) Discuss any limitations of elements being used in relation to their underlying formulation ( e.g use of shallow shell theory or cylindrical shell theory).

 

Endowed Professorships and Faculty positions in Health

Submitted by Gregory M. Odegard on

Michigan Technological University invites applicants for new tenure-track positions at any rank in the broad areas of health sciences and engineering. This campus-wide Strategic Faculty Hiring Initiative (SFHI) is projected to bring up to ten new faculty members, including possible endowed positions, to campus over the next two years to strengthen the key focus areas of biochemistry, bioengineering, bioethics, biomaterials, biomechanics, human factors, medical informatics, cell biology, physiology, and statistical genetics.



Bondary conditions of plate segment

Submitted by Mike W. Long on

Hello,

i'd like to model only one small segment of a large elastic plate. This plate is uniformly loaded by sinusoidal dynamic load.

The question is how i kann describe the boundary of this small segment, whose boundaris changes over the time. Is it possible to model the boundary conditions of this segment without consideration of its connection to the large plate.

I hope on your help.

Mike
