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.
