Researchers have developed a practical way of studying the intralaminar crack propagation of unidirectional fiber-reinforced polymer composite (GFRP) laminate.<\/p>\n\n\n\n

The novel approach was also implemented by finite element analysis (FEA) and validated by a tensile\/compression experiment. <\/p>\n\n\n\n

A lead researcher Changfang Zhao from Nanjing University of Science and Technology said that a new way can be used to complement the inspection of laminated structures that are used as primary structures in many industries.<\/p>\n\n\n\n

According to research<\/a> the novel approach using FEA was conducted using a progressive damage model (PDM) -which was executed by using the implicit user material (UMAT), explicit user material (VUMAT), the extended finite element method (XFEM) subroutines completed by a microscale model of crack propagation that was implemented using a representative volume element (RVE) algorithm. <\/p>\n\n\n\n

The results from the predictions agreed very well with experimental results from mechanical testing and scanning electron microscopy (SEM).<\/p>\n\n\n\n

In addition, using a blended approach for FEA simulation, namely by combining the PDM and RVE with XFEM subroutines, could be a step forward in simulating the intralaminar crack propagation phenomenon in order to gain deeper insights into the micro-macro failure mechanism.<\/p>\n","protected":false},"excerpt":{"rendered":"
