Studies of the buckling of composite plates in compression

Energy based collocation method to predict progressive damage behavior of imperfect composite plates under compression

“…According to degradation model presented by Hayman et al (2011) and also in order to better comparison with the results obtained by Yang et al (2013), the transverse shear stiffness matrix n Q is not degraded during the damage analysis.…”

“…The mentioned proposed formulations should be verified through a number of comparisons and this is done by comparing the results with those obtained by Hayman et al (2011) and Yang et al (2013). For this purpose, the plates which are considered in this study are square plates ( Table 2 as taken from Yang et al (2013).…”

“…Several simplified semi-analytical methods have been purposed by Brubak and Hellesland (2007a,b, 2008, 2011 and Brubak et al (2007c) for investigating the strength of stiffened and unstiffened metal plates with imperfection and cutout. Accelerated analysis techniques were proposed by Orifici et al (2008) using FEM tools such as ABAQUS to model the degradation and fracture mechanics of composite stiffened fuselage panel in a postbuckling regime.…”

“…Accelerated analysis techniques were proposed by Orifici et al (2008) using FEM tools such as ABAQUS to model the degradation and fracture mechanics of composite stiffened fuselage panel in a postbuckling regime. Some experimental works with comparison by FEM analysis can be found on ultimate strength of composite plates such as study investigated by Hayman et al (2011). These studies are included a parametric Latin American Journal of Solids and Structures, 2018, 15(4), e35…”

Failure investigation of top-hat composite stiffened panels

“…This makes modelling composites complex and often nonlinear. Considerable research has been carried out for the linear static, dynamic, buckling and failure analyses of stiffened plates/shells using finite element approaches (Prusty and Satsangi 2001a, 2001b, 2001c, 2001dPrusty 2003;Prusty et al 2005;Blake et al 2009;Hayman et al 2011;Tsouvalis and Garganidis 2011;Yang et al 2011;Hashim et al 2011;Gaiotti et al 2012) using an arbitrarily oriented stiffener formulation which was further expanded to geometric non-linear analysis (Ojeda et al 2007). Full scale experiments on the failure investigation of stiffened and unstiffened composite panels under transverse loading for the failure strains and loads were carried out by Stadke and Prusty (2004); whereas single level delamination and debonding of stiffener to plate was investigated using fracture mechanics approach (Mikulik et al 2006(Mikulik et al , 2008.…”
