We've followed the steps to apply a front impact force of 40g and 4g. Both times we got a stress singularity with an unusually high value of stress at a single element ( 5500 MPa and 505 MPa respectively) We have made sure that the mesh quality and geometry is up to the mark. PFA a screenshot of the 2D element stress contour of our model. Kindly offer some suggestion or guidelines to solve this problem at your earliest convenience.
Hi Everyone, I was performing on my model through creating Stress-Strain curve and putting data values as per the curve given below. I have used NLPARM in Load Step. The error it is showing is quoted as : "The plastic material data specified on the TABLES1 bulk data entry ID=5 is invalid. The slope after the initial yield point is not less than the Young's modulus. ( 1.468927e+005 >= 1.550543e+005 ) at the segment 2. " I got, that the slope after the initial yield point should be less than the young modulus. So, I have ensure that very carefully in my curve but also it is showing the same error. Kindly clear my doubt as if I am doing something wrong. Thank you for reading and for answering. Enclosure: In the curve I have selected the first curve among all the curves.
