Hello,

I am looking for some data/pictures of crack propagation tests. More precisely, what I am looking for are test results of some 2D structure (or structures that can be modeled in 2D) where the experimenter has listed the geometry, material, loads and boundary conditions, and displayed photos of the crack that was observed propagating on loading the structure. Sort of like "heres a plate of dimensions a x b, made of material x, with an initial crack here, I now apply a load of magnitude M, and heres a picture of the crack that has propagated."

Is there anybody who are still studying elastic vibration theory?

vibration theory

I'm a graduate student studying the coupled elastic vibration prolbem of structures and soils. However, I'm not very interested in that, as I think the practical coupled structure and soil vibration problem is totally inelastic, and I don't think it is of great importance to study the elastic case.

Is there anybody studying the vibration problem here and can you tell me what's the importance of studying the elastic vibration problem? Are you interested in inelastic vibration prolbem?

faculty opening

The Mechanical Engineering department at the University of Houston has an opening for a non-tenure track instructional faculty position. The ideal candidate should be passionate about teaching will be expected to teach 3 undergraduate courses a semester and help with ABET. A competitive 9-month salary is expected and summer support is possible as well. Although the position is non-tenure track, our intention would be to hire someone for the long-haul.

hai,

my project is analysis of functionally graded plates for thermal loads using matlab in this regard i need certain basepaper regarding "bending,buckling and vibrational analysis of composite laminates(cross-ply & angle-ply)subjected to only thermal loads(i,e temperature increment) either constant or linear change using different theories as classical laminate plate theory(CLPT),first order shear deformation theory(FSDT) and zeroth-order shear deformation theory(ZSDT)"

How to update solution-dependat variable (SVARS) during iterations

Submitted by haghighat on Thu, 02/09/2012 - 01:07

User subroutines in ABAQUS

Hello everyone,

I am implementing a uel user subroutine in ABAQUS. This uel is for modeling contact in X-FEM framework. Thus, it's a nonlinear problem and I need to store some solution dependent variables during each iteration. I know I can store SDVs in SVARS. But this vector will update at the end of each step, and not during iterations. Anybody knows about this problem?

I really appreciate if anybody can help me with this.

Thanks

constrained layer damping

Hi,

I am simulating constrained layer damping with viscoelastic layer in Abaqus.

Used 3D continuum element - C3D20R for base an face sheet and and same with hybrid

formulation C3D20RH for visco tape.

In FE mesh, I tied the nodes (through tie constraint) of base with that of visco tape and

also the visco tape with that of face sheet. But in the deformed mode shape, I am finding

Benzeggagh-Kenane (BK) criteria

Dear all,

Can anyone tell what kind of value of power i need to use for a PU glue? At the moment i am using the Benzeggagh-Kenane (BK) criteria.

Or will it be better to use the power-law mixed mode criteria for a glued in rod in timber?

I look forward to receiving your answer,

Ronald
