Hi......
I have a accelaration vs time data for an earthquake. But I need velocity vs time data for an earthquake for dynamic analysis of a structure with this earthquake as input. The intrgration of accelaration is velocity. How I can integrate this numerical data? I have an idean about Newmarks beta method but how to use it? I have no idea. Is there any further simple method to do this? Is there any reference book or journal or link available for this?
Thanks in advance......

Hi all,
cylinder with circumferential crack
hi...i m doing 2nd year mtech...i m getting an error while solving circumferential crack in cylinder using ANSYS...while calculating stress intensity factor(SIF) it shows the error as "all crack face nodes do not have the same z value in the currently active coordinate system"...please anyone let me know how to deal this error??
regards

Cohesive Zone Models are elasticity
I have always, and I believe correctly, considered cohesize/bridging models linear elasticity. This is because whether we apply them to holes or cracks, we are solving the equations of ELASTICITY, with nonlinear boundary conditions along the part(s) of the crack along which a traction-separation law is applied. So the material model is totally elastic. All we did was to augment the elasticity theory with an ad hoc physical condition (inspired by experiments such as Dugdale).
