Abstract:

Numerical simulations based on finite element modelling are increasingly being

developed to accurately evaluate the tensile properties of GLARE (GLAss fibre REinforced

aluminium laminates). In this study, nonlinear tensile behaviour of GLARE Fibre Metal

sweep mesh of a dome in ANSYS

Submitted by tunl on

I am dealing with a partial sphere dome in ANSYS, I created the volume by extruding half of an arch area along the axis at the dome center. I am using SOLID65 elements. The problem I am facing now is how to properly sweep mesh the whole volume ( actually, there are four 90 degree partial sphere together after the extrude of the area), because if I simply sweep the volume, the elements around the top center of the sphere will cause element shape warning in the static analysis.

Dose anyone have any idea about how to deal with the mesh around the center? 

 

orthotropic nonlinear viscoelasticity/creep in Ansys

Submitted by André on

Hi,

 I would like to know if there is any chance to simulate orthotropic nonlinear viscoelasticity/creep of CFRP in ANSYS (e.g. by means of user programmable features (UMAT subroutines) or using the software DIGIMAT or others)? For the nonlinear part I would like to use Schapery's method.

 Many thanks for yor help!

Dear friends,

 I'm an MSc. student at Bogazici University, Turkiye and I'm working on a thesis project about the failure behaviour of fiber reinforced laminated composite plates under different loading types. The material which we use are AS4 fiber reinforced  prepregs and their mechanical properties are the following:

 


E11 =134,000 MPa

E22 = E33= 9480 MPa

G12 = G13= 5490 MPa

G23 MPa =3272

nu12 = nu13 =0.271

 

nu23 =0.448
