How to run static and harmonic analysis in ANSYS APDL?

Hello. I am new to APDL. I am taking help from the documentation for modeling a simple beam. I want to apply 10kN static load at midpoint, then unload it to zero. Then i want to run the...

How to achieve the declining branch of load~deformation in tensile testing of plain concrete prisms?

I am trying to create load~elongation, stress strain, stress~CMOD relation of concrete prisms in tensions. I have done preliminary 4-point flexural tests on RC prisms, the prisms fail suddenly and...

Why are there 2 peaks in FFT of response of harmonic excitation in ABAQUS simulation?

I recorded the displacement response of a concrete beam. I excited it with harmonic excitation with 30Hz frequency (less than resonant frequency which is 43Hz). In the figure attached, the graph...

ABAQUS: the natural frequency from simulation is quite more than the experimental results

I am currently modelling a reinforced concrete beam in ABAQUS software. It's incremental static loading that goes from STEP 1: zero to 10% (of the maximum allowable load), then zero. After this I...

Can strain measurements from RCC beam be related to damage identification?

Vibration methods are used to approach changes in natural frequencies of the intact/damaged (concrete) structures and damage detection is only possible if the damage is significant. Stress-strain...
