    Complementary study material for FEM

    Thanks for the advice, this is exactly the response I was hoping for. I'll definitely search out the recommended books, and likely I will focus at a later stage. I will be working in a consulting environment so I will be covering a wide range of problems before I start to specialis in a specific...

    Complementary study material for FEM

    Hello, as I come to end of my degree I feel like I have consumed so much knowledge some earlier more fundamental topics have inevitably been pushed out of my brain! Whilst I have an appreciation and understanding of general engineering concepts, such as mechanics, calculus, matrix algebra etc...

    Non-constant E total, could it still be correct?

    Hello, I have been reading around online and it seems that this should remain (at least fairly) constant throughout the simulation. I am modelling a bi-stable structure that has an analytical rigid part to move the object into its second stable state, by pushing it in a certain direction...

    Is outsourcing services killing careers?

    Hello, I came across this article which is discussing the average salary of chartered engineers in the UK (£63,000), there seems to be a debate about the accuracy of this figure but the statement chartered engineer spans a rather wide spectrum. What I found interesting however, is that one of...

    Levels of design engineering

    Sorry if this is in the wrong forum. I was unsure where to put it! Just wondering as a mechanical engineer what the different levels of design engineering are. I was recently talking to someone at a large construction and chemicals company who expressed themselves as design engineers, in the...

    Working abroad (and long term travelling)

    Hi everyone, I am currently a student but will be graduating this summer. I hope to save up enough money to be able to go travelling in a couple of years. Whilst I would like to travel for a year or so I am also exploring the option of living abroad and potentially living and travelling long...

    large compay or small consultancy?

    With either company I will likely be there for a couple of years only, due to my partner living else where in the country. So my thinking is stick it out with the larger company, generate some savings or go with the smaller company and gain potentially a wide range of skills. Although with...

    large compay or small consultancy?

    Hello. I am currently deciding between two job offers. I am a graduate however I will be going into work not on a graduate scheme as I am trying to focus on CAE specifically FEA. One offer is for an incredibly large company working in a specific area of FEA. The other is a small consultancy...

    Decisions as an engineering graduate...the trade off between passion and money?

    Thank you all for the replies, glad to have sparked off a debate! I will be pursuing an engineering career and focusing specifically in an area I am interested. A lot of schemes appear to hold you in a technical position for several years then offer you the option of moving up to management if...

    Decisions as an engineering graduate...the trade off between passion and money?

    Hello everyone, I'm posting this topic because I believe this is a debate that affects a lot of young engineers making key decisions at the moment, including myself. There's a diverse mix of engineering students university, everything from hating engineering and wanting to get out as fast as...

    Confusion with categorising solvers

    DrBwts your comments are very insightful but I am unfortunately left confused, I am new to this software and these solver methods so please bear with me. So the system of non-linear equations in my dynamic implicit analysis are being approximated by Newtons Method then the outcome from this is...

    Damping in a dynamic model?

    I see what you mean, and i appreciate your comments but I'm still confused regarding how the program is actually implementing a quasi static application, you say it is increasing the damping but the section taken from the manual clearly states it is introducing inertia into the system. Is the...

    Damping in a dynamic model?

    And is that how it is achieving the quasi-static behavior? By introducing damping? Here is a quote from the Abaqus theory manual, the section in bold is what is confusing me, as you say damping is being introduced, affecting the inertia (increasing it?) •Quasi-static applications are...

    Damping in a dynamic model?

    im assuming that because in the step 'other' tab the "initial acceleration calculation at begining of step" is set to "Bypass". Now i may be incorrect on this, because I've just been looking through the Abaqus manual and it says Quasi static applications introduce inertia to stabalise the...

    Damping in a dynamic model?

    In a static analysis we are solving: [K]{x}={F} In a dynamic analysis we are solving: [M]{x''}+[C]{x'}+[K]{x}={F} Now by introducing a quasi static problem, the initial acceleration at the beginning of each iteration is 0. so we are left with: [C]{x'}+[K]{x}={F} As I have not specified...
