Stress concentartion factors in the beams with hole under pure moment

stress concentration factor

Dear All,

I have a beam with a hole under pure bending moment. I am very intrested to know is there any

relationship between the moment in the beam section and the stress concentartion (specially tensile stresses due to moment ) around the hole?

Any help will be highly appreciated,

Thank you,

Manooir

Tsai-Wu failure criteria Timber beam ANSYS

I am a PhD student on Timber structure.I have modelled timber beam using solid 45 element as 4 points bending but my result is overestimated.I have reviewed the literature and I have found that assigning Tsai_Wu failure mode in timber can solve the problem.I have found Tsai-Wu in following category in Ansys 12.1:Material model/nonlinear/inelastic/non metal plasticity/failure criteria/criteria3But Ansys appears the following error:*** ERROR ***

high speed impact

i am doing my mtech project on ballistic imapct of composite plates.i want to include the shock wave response of the material in the vumat code.can anyone provide useful suggestions regarding this?i also want to know can we plot the output results using the vumat code?if its possible what is the command line for that?

impact damage due to laminar construction??

laminar construction

Hi everyone,

 

According to a book chapter written by NL Hancox, 'Laminar construction of composites which is required if the reinforcing fibres are to be used efficiently and anisotropy reduced, can be a reason why composite laminates are vulnerable to impact damage.'

Now I have three questions;

1-What is meant here by the specified 'laminar construction to reduce anisotropy'?Does it mean to use different orientation for fibres in each ply to have an isotropic material at the laminate level?

Pressure distribution in hydraulic fracture

How to calculate the pressure distribution in hydraulic fracture? dp/dx=-12*u*Q/w^3 for Newtonian fluid,  If I do not assume the pressure in the tip equal to the normal stress.    

 Could I calculate the pressure of each element from the wellbore ?
