Each year, several new students begin their studies of Solid Mechanics for PhD degrees at Harvard School of Engineering and Applied Sciences.  The students come from all over the world.  We have no constraint on where they come from.

plane stress problem in abaqus

Submitted by prasadkulkarni on

hi all!

i am a new user of abaqus. i am trying a simple problem of a plate. the plate is made of composite material (orthotropic). i give all the properties correctly. but after submitting the job i get an error that 'laminate type- can be used with plane stress elemnts only'. how could i rectify this? can anyone tell me how to model a plane stress problem in abaqus? what is the significance of plane stress/strain thickness ratio. 

Design Web pages for easy reading

Submitted by vinshe82 on

Long line Text is very difficult to read so whiled designing web pages , it
is a good idea to avoid wide text
running from one side of the screen to the other. For this control the length
of your text by creating HTML tables that are fixed in pixels rather than in
percentage. The best width for line is between 65 -75 character. It's more
important for Web page design to make your text readable than to fill every
inch of the screen. Avoid large text blocks break up text into smaller sub-categories.
