Hi all,

I am looking for ANSYS-LSDYNA tutorials. If anybody has, I request him/her to kindly share or post the links.

Thanking you,

With best regards,

Hi All,

I am very new to FEM process and ANSYS as well. 

I am trying to do a plane strain problem (2D) in ANSYS. 

My problem is  I dont know how to model primitives like sphere, cube, cylinder etc for 2D plane strain problem.

Like say can i model circle of 20mm radius for modeling sphere of 20mm radius???

Or can i model square of 50mm length for cube of 50mm.

May sound very dumb, but this is my geniune problem 

Thankyou for your time and help (in advance) 

国内高速公路和城市高架大量采用独柱墩设计，近年已发生多起倾覆坍塌事故。以笔者来看，设计规范需要改进，特别在倾覆核算的要求和引导上更全面并提高安全系数，设计不够严谨是另一原因。

从结构力学来看，两个问题：

1.许多的独柱墩设计为何不加盖梁？仅为美观（相对成本应较小）？如加盖梁发生的几起倾覆坍塌事故应该都可避免，全国范围天文数字的高速公路和城市高架加固改造资金可大量节省。。。。

2. 独柱墩（特别是单支点）的抗震性是如何考虑的，比如在京津唐地震带。。。。

hi,

I made a model for concrete beam , and apply the load as load steps, and
then I made static non-linear analysis , but.....how con i define the
critical or the ultimate load that the concrete beam can stand before
collapse and how can I now the results for each load step? how can I
draw the (load - deflection)curve for the beam???

thanks.

Hi,

Do anyone know how to introduce ovality into a circular model in ansys.

Thanks

      i am a student of 4th year mechanical engineering.

I am trying to solve elasticity equations by Finite Differnce Method using matlab. i am feeling some problems in applying external loading in form of distributed load. i have discritized the displacemet equation but unable to apply distributed laoded in form of deformation. Can some one help me how to apply stress boundry condition (neumann BC)?
