Dear all,
I have a puzzling question.
As we know, the positions of a increment in a FEM analysis ( in abaqus) include :
1. the start of the increment 2. the end of the increment 3. the current increment etc
It is easily understood. But the data transfer process in different subroutines have me puzzled.
For example: Subroutines of ABAQUS
hi plz help me in doing fatigue problem in ansys classic if u have tutorials plz send it to me its my kind request....monday is last date for me to submit..plz help me
Dear All,
I am trying to simulate mechanical behaviour of a concrete unit cell for uniaxial compression laoding. I have apllied periodic bounadary conditions on both lateral edges using linear equation option available in ABAQUS where as on top and bottom edges load is apllied. Deformed structure shows there is no lateral deformation and unit cell behaves as if it is confined laterally on both sides. I am confused about my boundary conditions whether they are correct or not.
Equation used to aplly periodic bounadary condition are
i make FEA for my master research in ANSYS PRO., i simulate a prestressed concrete beam with two precast units connected by contact element (CONTA.52). i used solid 65 for concrete modelling and link 8 for for prestressing steel with initial strain, i entered the stress strain curve for the concrete with linear isotropic, concrete and multilinear isotropic in five points as below:
strain=0.0004 stress = 12 Mpa
Strain = 0.001 stress = 30 Mpa
Strain = 0.0015 stress=37.5 Mpa
