    Excessive inertial forces when starting a constant rotary speed model in Dynamic/Explicit

    Hello All, I'm analyzing the stresses in a crankshaft. The crankshaft rotates at a constant speed. The problem is when the simulation starts the stresses go from 0 to 1800 MPa (much more than the elastic limit), due to the inertial forces (high initial acceleration to pass from 0 to 224 rad/s)...

    Visualization with Dynamic/Explicit

    Dear all, I'm simulating a crankshaft with a constant rotational velocity and a varying load with Dynamic/Explicit. Although I have written a predefined field with the rotational velocity, in the module visualization, the crankshaft doesn't rotate, even though it appears the stress field of the...

    dynamic analysis of a crankshaft

    Hello, I only have two or three month of experience with the Abaqus. I'm facing now a problem related with a crankshaft (with just one counterweight). It is expected that I have to analize the crankshaft dinamically. My doubt is, once I have defined the contact elements in the joint with the...
