The effect of atmospheric conditions on the swing of a cricket ball
A report published in Procedia Engineering suggests that the 'phenomenon of swing bowling, in which a cricket ball veers sideways during flight, is not influenced by humidity'...

Need help in Creep modeling in ANSYS
Can Anyone help me how to do creep modeling in ansys?
I need to follow the creep law __> effective creep strain (e at time t) = S. T. e^(-H)
S=(a0)^t.(sigma)^(a1) ; T = t^(a2)+(a3).t^(a4)+(a5)t^(a6) ; H = (a7)/[(theta)+273.16]
a0 to a7 are material constants.
I have the experimental data and tried to fit the curve in Ansys to obtain the material constants.
I tried to follow the ansys help file steps. But facing erros messages.
Nanocomposite Electrical Generators....
A nanocomposite electrical generator composed of an array of zinc oxide nanowires is considered.
The electric potential distribution along zinc oxide nanowires is modeled using continuum
mechanics and Maxwell’s equations for the case of axial loading. A perturbation technique is used
for decoupling the constitutive equations. The governing differential equations are solved using a
finite difference method. It is shown that a gradient of electric potential exists along the axis of the
zinc oxide nanowires. Maximum and minimum values of electric potential exist at the extreme ends
along the nanowire length and have opposite signs. The positive and negative voltages are separated

Rupture of a highly stretchable acrylic dielectric elastomer (VHB)
Dielectric elastomer transducers are often subject to large tensile stretches and are susceptible to rupture. Here we carry out an experimental study of the rupture behavior of membranes of an acrylic dielectric elastomer (VHB 4905). Pure-shear test specimens are used to measure force-displacement curves, using samples with and without pre-cracks. We find that introducing a pre-crack into a membrane drastically reduces the stretch at rupture. Furthermore, we measure the stretch at rupture and fracture energy using samples of different heights at various stretch-rates. The stretch at rupture is found to decrease with sample height, and the fracture energy is found to increase with stretch-rate.

Modelling crack propagation using XFEM in Abaqus (Fracture Mechanics)
HI,
I am using XFEM to model crack propagation in thin aluminum panles using ABAQUS. The reason for modelling it is to check my numerical model against the results published by Lyonel Reinhardt, t, J.A. Cordes in the paper XFEM Modeling of Mixed-Mode Cracks in Thin Aluminum Panels (http://www.3ds.com/fileadmin/PRODUCTS/SIMULIA/PDF/scc-papers/Def-XFEM-Modeling-Mixed-Mode-Cracks-Thin-Aluminum-Panels.pdf)
