Simulation of a bolted T-stub with ABAQUS

About one year ago, I tried to analyze a bolted T-stub to test the analysis method of bolted connections and verify my abaqus model referring to a journal paper, unfortunately, I could not find that paper now. Though I would not focus on steel connections in the future, I still want to make a summary of this simulation in order not to waste the effort one year ago. Due to the symmetry of this stub, only half is modeled as

Fracture analysis of a metal specimen

I analyzed a specimen of ductile material with explicit dynamic method about one year ago. Recently, I want to review the model and summarize the process of analysis. Stress and strain of material in ABAQUS Stress and strain in the definition of material in abauqs should be converted to true stress \(\sigma\) and true plastic strain \({\varepsilon _p}\) from the data obtained in experiments. The stress and strain achieved in experiments are engineering stress \({\sigma _{{\rm{eng}}}}\) and engineering strain \({{\varepsilon

Warnings on keywords when importing input file to ABAQUS

I want to analyze a steel frame with pin connections at both sides or one side at some beams. I found the keyword *Release is very useful and convenient, so I resort to this keyword. I wrote the input file with the same syntax rules, so that it will be more convenient for me to establish more models. However, when I try to run the input file, there are warnings and errors even with the input file generated from a

Transverse shear stiffness of beam in ABAQUS

Calculation of transverse shear stiffness Definition The effective transverse shear stiffness of the section of a shear flexible beam is defined in Abaqus as \[{\overline K _{\alpha 3}} = f_p^\alpha {K_{\alpha 3}}\] where \({\overline K _{\alpha 3}}\) is the section shear stiffness in the \(\alpha \)-direction;  \({K_{\alpha 3}}\) is the actual shear stiffness of the section having units of force; and \(\alpha = 1,{\kern 1pt} {\kern 1pt} {\kern 1pt} 2\) are the local directions of the cross-section.  \(f_p^\alpha \) is a dimensionless factor used

Beam elements in ABAQUS

Beam elements in ABAQUS make me a little confused, especially about the shear stiffness and elements for open sections. In this post, I want to make a summary of the elements in ABAQUS and give an example about the settings of beam elements. Beam element library Beam elements in a plane only have active degrees of freedom 1, 2, 6. Beam elements in space have active degrees of freedom 1, 2, 3, 4, 5, 6. Open section beams in space B31OS,
