While analysing through ANSYS We have to give the strees strain curve for fibre reinforced concrete. How stress strain curve for fibre reinforced concrete is given while analysis.I have tested compression stress on cylinder and have stress strain curve for compressive test on cylinder
I want to know about the basics of stroh fromulation and its application in Piezoelectric material.I didn't find the basic lecture notes or the material regarding that on the internet.

hello eve1,
i m facing some problem while trying to mesh a horse shoe type structure, when i define the element type as solid 8 node 70 (brick8 node 70) it gives me error saying cannot apply coz it violaets the ASME code or some hting like that....plz help me out wiht what element type has to be defined for the HORSE SHOE type structure...............or whether to define the semi-circular portion seperately (with wat typr ) and the bottom portion seprate.
Hi All
I am trying to implement a composite material model in vumat. So far, I
have been successful in getting the correct results for a cube for both
tension and compression with the cube being modeled with just one
element (C3D8R)
But when, i model the same cube (side 40mm) with 125 elements,
subjected to the same bc's, with the same material parameters, i get an
error that the element is undergoing excessive distortion.
I am specifying a density of 1.52e-9 ton/mm3.
Ideally, this post of mine should carry a poll, but I guess as an ordinary user, I cannot insert one.
Currently, I am writing a small software program that is especially designed to help learn FEM. For instance, I will be providing detailed listings for every intermediate step, e.g. all those [D], [B], [k], etc. matrices for each element, as well as the final assembled global system {F} = [K]{d} and its solution separately at each Gauss point. Only linear static problems for the time being; will add transients/eigenvalue problems in near future.
Hi ,
Due to Thermal ratcheting in cylindrical pipes carrying hot fluids that are used in nuclear applications, the pipe bulges. I am about to start a project to study why this bulge comes and how to rectify it. It would be very helpful to me if some of you can give your valuable suggestions and references in the area of Thermal Ratcheting in pipes.
Thanks and Regards,

Myocardial fiber orientation is a topic that has recently received much attention in connection with cardiac pumping function. The twisting motion of the cardiac base to apex can be a direct result of this geometric orientation of these fibers. One important question that has not been addressed yet is whether there is any relationship between the contractile energy expenditure and the geometric orientation of myocardial fibers. In the present work, we study the effect of contractile fiber orientation on pumping function.
Hi!
I`m new to this webpage, and hope for some good answers for use in my masters degree within fatigue. Currently I`m working on calculating the total life of a gusset specimen using strain based fracture mecahnics. I`ve read som articles on the topic, but have some difficulties on understanding the calculations itself. I`m using Excel in the calculations. If anyone has an excel-sheet, or other ways of helping me, I would hihgly appreciate it.
Thanks, Sean Angus
