    Photoelastic Stress Analysis

    Thanks all. It was basically just a curiosity thing. I have done FE Analysis on the assembly but since I am mechanically testing it anyway, I thought it would be interesting to find out the stresses in the material while testing. Also, I thought that a photoelastic coating could be applied to...

    Photoelastic Stress Analysis

    I would like to do a dynamic stress analysis of a dovetail joint assembly. I am curious about photoelastic stress analysis and how it works exactly. The whole dovetail assembly is about the size of a dice and is made from Inconel 718 and a stainless steel. Is there a 'simple' way to do...

    Multi Axis Load Cell

    I need a light weight force transducer to measure forces up to 2000N in Fz and approx 1000N in Fx and Fy. I have looked into purchasing multi axis load cells but the ones which are lightweight and small do not measure loads up to these values. I am interested in making my own load cell so any...

    Strong 0-80??

    Thanks for all the info. Metalguy I have looked into getting 17-4 stainless steel 080 custom made but I cannot find anybody willing to make anything of this size. My machine shop does not have the capabilities to make something this small. Yates I have checked out Inconel screws but again I...

    Strong 0-80??

    Hi all I am currently using 0-80 3/16" stainless steel button head screws in an application to hold an inconel plate onto a stainless steel material. However I am finding that this type of screw yields when loads are applied to the assembly. These loads include axial forces and moments...

    Is future study necessary?

    Continuing to do a masters or PhD means I can get the highest level of education possible? Could I not gain more education from joining the workforce and learn in a more practical manner? Also if I do a PhD, I have been told that I could be overqualified (and confined to one area of expertise)...

    Hardness/Tensile Strength

    I am trying to find the ultimate tensile strength of a viscoelastic material. Access to the material is confined in that I have only access to its surface. I have looked into finding the shore hardness of the material and then converting this into an ultimate tensile strength. However I have...

    Masters/Phd???

    I am still at the stage where I can do either a masters in one university or a masters progressing onto a PhD in another university (in Computer Assisted Surgery). I do not see myself teaching in a university in the future. This is the main reason why I wouldn't do a PhD. Also, I realise a PhD...

    Simple Spine Model

    I am involved in research examining forces on the spine during scoliosis surgery, but I would like to make a simple spine model in the lab so that I could visualise and simulate what happens to the instruments during surgery. Hooks that "hook" on the the tranverse process and pedicle...

    Masters/Phd???

    I recently graduated in Mechanical Engineering and I am currently employed for 1 year in research of intra-operative forces during spine surgery. I want to get into the bioengineering area and am considering returning to school to do either a Masters or a Phd. However I am unsure as to which is...

    Is future study necessary?

    I am currently employed to research intra-operative forces during spine surgery. I am considering returning to school to do either a Masters or a Phd but am unsure as to which is more beneficial. Any tips?
