Hello to everyone.

The question is as:

I want to introduce the critical fracture energies (Gic,Giic) in a mixed mode fracture analysis in Abaqus using the XFEM  or the cohesive simulation method.My material can be considered as linear, the problem quasi static and the material properties E,v and yield strength known.

i am doing project on how crack growth and which direction growth. in 2d and 3d model using anasys. so i want calculate stress intensity factor how it is calculate bt using j integral method. this project totally numerically.

Thank you, Ares, for your kind introduction. I am greatly honored to have my name added to the list of Timoshenko Medalists. However, receiving the Timoshenko Medal has a down side. I'll describe the down side through a story told by Jean-Baptiste Leblond. At the circus in Imperial Rome a slave was thrown to the lions. The lion stalked the slave and then attacked. As the lion jumped on him the slave grabbed the lion's mane and whispered in its ear. To the crowd's amazement the lion slinked off into a far corner of the arena and sat down. The Emperor called the slave over and said “If you tell me what magic you worked I'll give you your freedom.” The slave replied “It wasn't magic. I just told the lion if he ate me he'd have a good meal but then he'd have to give an after dinner speech. “

Fortunately for me, many previous Timoshenko after dinner speeches are available on iMechanica. I will follow several of those and talk about my life in mechanics. Before I start on that, I want to mention four mechanicians who have had an enormous influence on my professional life as well as having greatly enriched my personal life: John Hutchinson, Viggo Tvergaard, Jim Rice and Erik van der Giessen. There is not enough time to detail my debt to them.

My life in mechanics began my senior year at the University of Pennsylvania. I took a course in continuum mechanics from Hsuan Yeh who was Dean of the Towne School. The course was so interesting that I decided that was what I wanted to study in graduate school. I went to graduate school at Harvard and was very lucky that a young faculty member named John Hutchinson agreed to be my thesis adviser. My PhD thesis involved the finite strain, finite element analysis of a two dimensional periodic array of circular holes (motivated by the pioneering ductile fracture studies of Frank McClintock and Jim Rice). This initiated me into two emerging developments in solid mechanics: finite element methods and materials mechanics. As John Hutchinson remarked in his Timoshenko Medal address, we did not realize we were participating in a revolution.

Good morning,

I'm dealing with an structrual static analysis of a shaft in Ansys WB. The shaft is supported by bearings and loaded by a torque. I tried to replace bearings with "Cylindrical support". (Radial - fixed, Axial - fixed and Tangential - Free) but I am not realy sure that this support work. Is it good manner how to replace this kind of support in 3D analysis because the Ansys shows the warning that about rigid body motion etc..

Thanks in advance.

Professor John W. Hutchinson, of Harvard University, will receive the 2012 Ludwig-Prandtl-Ring.  The award is the highest honor bestowed by the Deutsche Gesellschaft für Luft- und Raumfahrt, the German Society for Aeronautics and Astronautics.   Ludwig Prandtl was a great pioneer of modern Aerodynamics.  The Ludwig-Prandtl-Ring is awarded annually to the maximum of one individual for outstanding contributions to Aeronautics and Astronautics.   

Dear,all

 Can ANSYS modelling tubular joint type Y in 3D with  a load in plane bending on brace?

hello,

 i am a student of NIT calicut trying to do project (FATIGUE LIFE OF GIRTH WELD IN PIPE).using ABAQUS.

I am beginer in ABAQUS.

SO can any one help me by sendin any tut of Crack formation and propagation of crack in weld joint in  ABAQUS 

THNAX,..... 

Solved! Thanks

Dear all:

Is there anyone to do simulation work on SAW or other fields? I really need your help.

I just want to apply the peridic condition (U(x+P)=U(x)exp(-j*beta*P), where P is the periodic and this euqtion is the Floquet condition which is usually used in SAW devices) for a SAW simulation with ANSYS. in fact, ANSYS provides one periodic code 'perbc2d' , but it is used in Magnetic fied. I am now very trouble in it.

Would you please give me some hints? Thank you very much.

how about applying symmetry or antisymmetry boundary conditions (DSYM Command)on two sides of geometry instead of periodic conditions?

Hi

I want to model a piston and cylinder in ANSYS FLOTRAN.
The piston is moving up and down sinusoidal in cylinder and the compressible
gas inside the cylinder is compressing and expanding with time. How can I model
this problem in ANSYS FLOTRAN?

Thanks,
