In this study, we built a numerical model to analyze the behavior of composite sandwich panels subjected to vibration. However, the sandwich panel was in the form of a shell, so it took a lot of time to perform simulations and build a CAD mode

Finite element analysis of reinforced concrete structures under severe and reversible loadings requires a proper representation of concrete material behaviour. Abnormal

The abilities of the ACI-318 shear design method and a simplified design method based on the Modified Compression Field Theory to predict the failure loads are compared. It is found that the ACI design method is
