iMechanica will be down briefly at 10 am this Friday

Just got a message from Lesley Lam, iMechanica user number 1, as follows.  Harvard School of Engineering and Applied Sciences IT is in the process of moving our servers to a faster, newer host.  As part of this process, I would like to take down iMechanica for about 10 minutes on Friday October 3rd at 10am.  I am hoping this will improve performance and reliability on the machine as well.

chimaney silencer + acoustic + ASME standard

Dear All my friends,

I have to design silencer at chimaney outlet. The silencer can be easily designed for mechanical strength as per ASME section VIII standard. But now I have to design the silencer from acoustic point of view as I have to consider the db level of the sound generated due to very high velocity flue gases.

 please tell me which ASME standard can I follow to meet the requirement from acoustic point of views.

thanks in advance,

 Regards,

Abhijit Nalawade.

 

Necking Analysis of Strain Softening Materials ...

Hi all.

I'm studying the high temperature viscoplastic behavior of titanium alloys. It is well known that at high temperature range, deformation induced dynamic recrystallization (DRX) causes dramatically strain softening. Such strain softening behavior is also treated as plastic instable according to literatures.

Journal Club Theme of Oct. 1 2008: Fluid - Structure Interaction, an overview of current trends and challenges

Choose a channel featured in the header of iMechanica: 

Starting with a solid mechanics background, I have been recently interested in fluid-structure interactions for applications in biomechanics of soft-tissues; and thought that the iMechanica Journal Club forum would be a good opportunity to share my personal experience and start a discussion on this challenging inter-disciplinary subject.

Unsolicited proposals on Dynamical Systems

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:

hydrostatic loading on inside and outside of ship shell plate

as you can see in attached, my model has been included too many small area, on the other hand hydrostatic and hydro dynamic pressure are gradient loads, so how we can apply these loads on inside and outside of shell plates as gradient loads?

Exact relations in the micromechanics of composites

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. 

The post LHC universe?

Most of you have heard about the commissioning of the Large Hadron Colider (LHC) by CERN and then the explosion of Helium followed by a postponement of operation until spring next year.  One of the worries some people had was that a mini black hole would be created by the collsions.  Also, the anthropic principle in one of its forms suggests that every possible universe exists but we see only our universe because it's the one in which intelligent observers exist.

Simple and highly accurate two dimensional finite elements for laminated composite structures

I have developed a set of simple and highly accurate two dimensional finite elements for the analysis of laminated composite structures. These elements are capable of accurately predicting three dimensional stress state (all six stresses) using constitutive law.  These elements reduce modeling effort, computational time and increase solution accuracy.

Can someone suggest me a proper source to support my research financially?

Mechanics of Microtubules Buckling Supported by Cytoplasm

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 Finite Element Method for Transient Analysis of Concurrent Large Deformation and Mass Transport in Gels

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. 

Viscoelastic properties

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. 

Buckling of thin walled cylindrical shell

I am analyzing a steel thin walled cylidrical shell subjected to axial compression against buckling.I performed both eigen value linear and nonlinear buckling analyses using ANSYS.The buckling load is less than the material yield limit and is therefore elastic buckling.

One of my colleague argues that the shell will regain its original shape after the buckling load is removed,as its is elastic buckling.My plea is that the shell has passed the limit point (buckling load) and it is global buckling and no shape recovery will occur after the load removal.

Topology optimization

I'm asking the group about the current and future challenges in topology optimization either from the theoretical point of view as well as the industrial or practical point of view. I think Homogenization is the current de-facto method for practical optimization and I can detect some tendencies like level set methods, mesh less methods, etc at the research level.

What do you think about which is the "predominant" current wave and which will be next wave in topology optimization in the above two fields (theoretical and practical).

Ansys Help

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.
