I am a newcomer to FEM and Ansys, so forgive the possibly banal question:
I have modeled a cantilever beam with a vertical point load acting at the free end using Ansys (using a PLANE42 element) and am slightly confused about the resulting plot for stress in y direction (y being the axis pointing downwards) versus y coordinate in the central cross-section.
The stress is mostly approximately equal to zero (which makes sense) except near the top and bottom surface of the beam, where it jumps abruptly to, respectively, a high positive value, and a high negative value. How could this be explained?
