    How to extract values of Knn, Kss and Ktt from experiments

    Hi there I'm just curious and hope someone could give me some lights on how to extract properties of adhesive such as Knn, Ktt and Kss from experiments. Which experiments do I have to perform? many thanks

    How do I change loading rate to speed up quasi-static simulation in Abaqus/Explicit?

    you have to specify onto the amplitude tabular in order to get increment and constant strain rate

    CFRP and GFRP

    hi there I would like to ask why is it carbon it self in the CFRP considered as orthotropic and glass in GFRP considered as isotropic? many thanks for your views and lights really appreciate it

    Tie constraint Interaction between two material (anisotropic and isotropic material)

    what happen in the tie constraint interaction between two materials having different material properties? is it strain compatibility? or some relaxation occur?

    how to change global axis in abaqus inp file

    Dear experts It may sounds easy and straightforward but I struggled to find way of changing global axis system (which relate to the odb results for stress, strain etc S11, S22, S33) do I have to orientate the parts (whole model that i formed) or do i have to edit the global axis system? If so...

    Material Properties of Carbon Fiber

    I have a bit of understanding now, especially when you said the geometry have influence on material properties so it seems vendor of carbon fibre as general couldn't give generic material properties for all direction then

    Material Properties of Carbon Fiber

    Do you guys know how can I justify that carbon fiber has isotropic / orthotropic material properties? if it is isotropic, how can i justify some papers suggest they are orthotropic? is it because when it undergoes curing process, in the oven it becomes elastic brittle (which induce to...

    Ramp loading in dynamic/explicit analysis

    abaqus explicit -dynamic loading will make use of amplitude rather than ramp

    Cohesive surfaces and tangential displacement

    I have tried to run your model but it appeared the error in the simulation as line 213 size growth rate, keyword error?
