stress concentration at the crack initiation location while operates at 120Hz frequency.how to do using abaqus software tool.Is there any one previously worked in this area.kindly assist me to resolve this problem.
The Dynamical Systems program in the Directorate of Engineering and the Applied Mathematics Program in the directorate of Mathematical and Physical Sciences Sciences, of the National Science Foundation, have just published a joint "Dear Colleague Letter", expressing interest in special topics in Dynamical Systems. The letter encourages unsolicited proposals on the following topics:
These days, I need to gain a shell structure's geometry information from Hypermesh. So I need to connect Hypermesh with Compaq Visual Fortran6.5. can some one give me some advices. thanks so much!
There are several exact relations from the theory of composites that can be used to determine whether a new numerical or analytical approach gives reasonable answers. Here's a paper on some exact relations that I wrote up a long time ago and just recently posted on Scribd.
hello sir
I am saravana,doing M.E,I am doing a project on C Clamp which has a hole at its centre,generally there are two C Clamp at right angles to each other,when one of the c clamp is modelled and rotated to make the other one at 90 degree,the centre of two clamp is not coinciding.so Please give me some suggestion
The cytoskeleton provides the mechanical scaffold and maintains the integrity of cells. It is usually believed that one type of cytoskeleton biopolymer, microtubules, bear compressive force. In vitro experiments found that isolated microtubules may form an Euler buckling pattern with a long wavelength for very small compressive force. This, however, does not agree with in vivo experiments where microtubules buckle with short-wavelength. In order to understand the structural role of microtubules in vivo, we (Jiaping Zhang and Hanqing Jiang) developed a mechanics model to study microtubule buckling supported by cytoplasm. We found that the ability for a cell to sustain compressive force does not solely rely on mic
A gel is an aggregate of polymers and solvent molecules. The polymers crosslink into a three-dimensional network by strong chemical bonds, and enable the gel to retain its shape after a large deformation. The solvent molecules, however, interact among themselves and with the network by weak physical bonds, and enable the gel to be a conduit of mass transport. The time-dependent concurrent process of large deformation and mass transport is studied by developing a finite element method.
Hi I am new to this blog as well as new to Viscoelasticity. I have some basic quiries on viscoelasticity...as I am beginner to this area.
I am working on a polymer viscoelastic fluid filled with abrasive (Silicon carbide particles) for finishing of metal surfaces.This composition (polymer viscoelastic fluid + abrasive particles) placed in a cylinder and pushed through the hollow cylinderical workpiece with certain extrusion pressure excerted by piston. Due to piston pressure, the abrasives in the composition will abrade the workpiece surface.
Hi All
I am trying to use Shell181 elements to model carbon/epoxy unidirectional composites. When tried to use anisotropic material model ansys wants me to enter coefficients D11 to D21. I am not sure how to calculate the value of these coefficients or where to get their value from. Some help in this regard will be much appreciated. Thank you

Hi All
I have just started my postgraduation in aerospace composites. I am new to FE of composites and required serious help in learning composite modelling. It will great if someone can help me in starting up. If you know any websites or books which have examples which I can go through to learn modelling of composites, please let me know. Thanks for your help.
Regards
Maajid
