Fem Definition and 21 Discussions

Fem2Fem was an American techno group in the 1990s who released three albums. With actress Lezlie Deane of Freddy's Dead: The Final Nightmare as a member, Fem2Fem were the first and openly lesbian pop group to chart, although the band did contain straight women in addition to open homosexuals. But only some of the members of Fem2Fem were lesbians, and according to Michelle Crispin their intentions at the beginning were to promote a healthy view of sexuality with their music, regardless of sexual orientation. However, an appearance by the band in the December 1993 issue of Playboy magazine and the non-political nature of their sapphic lyrics led to criticism by some in the LGBT community that the band was trying to make a fast buck off playing to the prurient interests of a heterosexual male audience.

    FEM, Matlab and the modes of an element

    Hello I wrote a Matlab code to form the 8 by 8 stiffness matrix of a single, 4-noded element, for a plane strain problem for an isotropic element. I conduct an eigenvalue analysis on this matrix Matlabe reports 5 non-zero eigenvalue modes, and 3 zero-eigenvalue modes (as expected) Of the 3...

    A A question about current density in finite element analysis

    I know that if there is only one conductor providing the current density, then the current density can be used. But if you apply Maxwell's equation when there are multiple current sources, I don't know which value to use. This is not an analysis using a tool, but a problem when I develop the...

    Engineering Book considering FEM analysis for complex eigenvalues (incl. damping)

    Can anyone recommend a book in which complex eigenvalue problems are treated? I mean the FEM analysis and the theory behind it. These are eigenvalue problems which include damping. I think that it is used for composite materials and/or airplane engineering (maybe wing fluttering?).

    What size is the Global Stiffness Matrix in this Example?

    does this Beam, composed of three elements and 4 nodes(considering lateral deflections and slopes) has an 8x8 global stifness matrix and if so is the global matrix calculated the same way as a 6x6 stifness matrix for the same kind of beam but only with two elements and 3 nodes

    Poisson ratios for Orthotropic materials (composites)

    I'm new to composite materials. I've studied mechanical engineering but I am actually usually involved in hydrodynamics (in which I've done my masters). However for a project we do fluid structure interaction with composites, and as these things go, you cannot get away with the 'black box'...

    Total energy (ETOTAL) is not zero and increasing (Abaqus)?

    Hi all, I have performed a small static analysis with one element (C3D8). The bottom face of element is completely constrained, and the top part is displaced. In the geometrical linear analysis, the internal energy (ALLIE) and the work done (ALLWK) are equal. So, with ETOTAL = ALLIE - ALLWK...

    Which strain tensor is used by Abaqus?

    Hi all, I have some doubts regarding the strain tensors Abaqus uses for the case of Geometrical non linear analysis. In the case of geometrically linear analysis, all the strain tensors will be equal to engineering strain, So it doesn't matter which strain tensor Abaqus uses. But for...

    Abaqus FEA Problem - Displacing an Entire Part at Once

    Hi all, I have a personal project I am working on in Abaqus CAE/Explicit 2017. I have a tube, that I am trying to advance into a larger tube with a bend in it. The idea is that the small tube enters and then deforms around the bend as it comes into contact with the radius of curvature of the...

    Methods for Damping High Frequencies in FEM Thin Film Model?

    I would like to simulate the vibrations of a thin film polymer in vacuum using nonlinear analysis. For this purpose I am using an FEM program I have written in MATLAB. I do not have any data regarding damping in the structure, so I am estimating the damping using stiffness-proportional-only...

    Friction-less / Friction contacts in Ansys

    As far as I know both the friction or the frictionless contact types in Ansys doesn't prevent motion in the perpendicular direction.

    Can You Help With Finite Element Analysis in Cylindrical Coordinates?

    I am trying to numerically calculate the electric potential inside a truncated cone using the finite element method (FEM). The cone is embedded in cylindrical coordinates (r,phi,z). I am assuming phi-independence on the potential, therefore the problem is essentially 2D; I am working only with...
