Hi freinds,
I have a model in ansys, I did modal analysis on it, but low frequency don't appear in it. in experimental results appear low frequency . please help me, why low frequency don't appear in ansys.

Hello everyone,
I want to model a connection between two steel plates which form a T-section. The welds are fillet weld. Do you have any recommendation how to model the weld? One way I think of is to connect the two plates with two solid elements weld through tie constraint. You think that's a right way of doing that?

Symposium Description

Abstract:
Pendulum tuned mass dampers (PTMDs) are used to passively mitigate the vibrations of tall structures and buildings. The main objective of this short note is to introduce analytical formulae for the optimum design of the linear PTMD coupled to an undamped primary system. Den Hartog's equal peak method is applied to derive the optimum design. With the mass ratio between the primary system and the PTMD, the optimum length and optimum damping of the pendulum are calculated. The formulae are presented in both dimensional and non-dimensional forms and are simple to apply in real applications. It is also shown that the vibration mitigation performance of the proposed optimum design precisely matches the results obtained by numerical optimisation techniques.

A USACM Thematic Workshop on Recent Advances in Computational Methods for Nanoscale Phenomena will be held at the University of Michigan in Ann Arbor from August 29-31, 2016. The workshop website contains further information at http://acm-nano2016.usacm.org.
The 2016 NAFEMS UK Regional Conference will cover a wide range of topics, addressing every aspect of engineering analysis and simulation during a 2-day program. The 2016 conference will bring together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum. Covering all aspects of the technology including FEA, CFD & MBS, the event will focus heavily on best-practice, use cases, state of the art, problem areas, developing fields and much more.
