@gravityandinertia, since the beam is modelled three-dimensionally and the load is applied as a pressure [kN/m2] on the upper side of the beam, there's no need to modify the load because of the symmetry.

In the model that I attached, it fails to converge for a ultimate bending of 216 mkN. Less than half of the hand-calculated.

Hi everyone, I'm trying to model a simple RC beam to compare the ultimate load of this simple structure model with hand calculations and verify that the difference in the results is small enough, in an attempt to justify that the model works properly and then use it to simulate a more complex...

All right! We'll try to take measures with an accelerometer. Thank you btrueblood, I appreciate your advices!

Thanks for your reply btrueblood. The point is that the second test (dropped block) consist of a specimen made of the same material but with different shape. The first specimen size was 40x10x10 cm and the second one was 50x50x50 cm. It's not only changing the load case, but also the shape and...

Hi everyone! We have experimental data (acceleration – time) in two points of a specimen made of a certain concrete (non-conventional), with a prism shape of 40x10x10 cm. The specimen was vertically oriented, with the lower end fixed and the upper end free. A vertical impact excited the sample...

Thanks Denial for your reply. I tried to make a finer mesh, but it didn't work. I got the same results. The horizontal strains are almost equal at the interface between different materials, but the vertical strain isn't (the load is also vertical), specially when the difference of the modulus...

Hi everyone! I need help to interpretate FEM results. I would appreciate some responses. I built a finite element model (using ANSYS) of a block (3D) composed by different horizontal layers, each one with different material properties (linear elastic). I used 3D solid elements. The boundary...
