Hello everybody, as part of my thesis I have to find typical values of fiber volume in GFRP composites for marine applications such as boats, ships etc. Until now, I have found some values approximately close to Vf=50% but not from sources that I can include into my thesis. Does anybody have any...
Hello everybody,
I have a simple question regarding the stresses through the thickness at a composite laminate. I have created a simple rectangular area with shell181 elements(KEYOPT(8)=1) and I have given a lay-up sequence through Preprocessor>Sections>Shell>Add/Edit. Then, I constrained one...
I have modelled a heavily welded structure in LS-DYNA and I am using implicit method to solve it as the problem is static. Which is the correct command (keyword) in LS-DYNA in order to model initial stresses such as the residuals from the welding procedure? I am using the keyword...
