“…The model is used to determine the homogenized, or "smeared," engineering constants of a multilayered laminate (figure 2). Significant features of the theory are discussed by Bogetti et al in (29)(30)(31) and an overview is given in this section. Equation 1 represents the effective stress/strain constitutive relationship for the laminate:…”

“…Ply-level stresses and strains must be extracted from structural stress and strain profile in order to conduct failure analysis. To deal with these issues, Bogetti et al implemented the well-established "smearing/unsmearing" approach (29)(30)(31). Equivalent laminate properties are generated by "smearing" the ply-level nonlinear, anisotropic material behavior of the layup and ply-level stress state needed for failure analysis is generated by "unsmearing" the elemental stresses and strains.…”

“…LAM3D was created by Bogetti et al (29) and uses orthotropic, linear ply properties and progressive ply failure to simulate the material point response of a laminate. The code determines the 3-D effective properties, ultimate strength predictions under mechanical and thermal loading, and effective stress-strain response due to progressive ply failure under mechanical loading of thick-section composites.…”

SUPPLEMENTARY NOTES ABSTRACTMaterial nonlinearity and progressive ply failure are important considerations in the finite element modeling of thick-section composite structures. LAMPATNL uses a method to model the material nonlinearity and progressive ply failure of composite laminates using finite element software without explicitly simulating individual plies. Improvements to LAMPATNL are documented and discussed in this report. Also, LAMPATNL is validated against both the linear and nonlinear material point models. In this work, a standardized process for designing composite structures with LAMPATNL using newly formulated output parameters, stiffness ratios, to analyze the nonlinear response and progressive failure of the composite structure is developed. These new parameters greatly improve the visualization of critical design information of the structure. Two case studies, an open-hole sample under multi-axial loading and a compressive shear sample, are evaluated using the design methodology. Coupling LAMPATNL with a design methodology and new stiffness ratio parameters demonstrates the utility of progressive failure and nonlinear analysis when applied to composite structures. The straightforward visualization of critical design information creates a unique approach to analyzing the design of thick section composites. This methodology represents a unique contribution to the modeling of composite structures that is not matched by any current composite model. iii

“…Kilic and Haj-Ali [51] developed an elastic degrading constitutive model specific to pultruded composites. In a follow up paper, Kilic and Haj-Ali [52] proposed a simple approach, which is readily amenable to computational procedures, for the progressive damage analysis of pultruded materials and structures, with a special emphasis on notched plates and pin-loaded bolted connections. The proposed constitutive and damage framework was integrated within the commercial FE code Abaqus [53] for a general nonlinear analysis of pultruded structures using layered shell or plate elements and was later extended to three-dimensional continuum elements [54].…”

A review of the behaviour and analysis of bolted connections and joints in pultruded fibre reinforced polymers

This paper presents a literature review of the state-of-the-art experimental and analytical methodologies adopted in the construction industry for the design of mechanically fastened connections and joints in pultruded fibre reinforced polymer framed structures. Results and conclusions obtained from the published literature relating to the effects of critical parameters, which include geometry, material properties, configuration, connecting components, fasteners, lateral restraint, etc. on the mechanical behaviour and failure modes are discussed in the light of addressing gaps in knowledge that need resolving to prepare design guidance that is reliable and robust. Further research required to improve the design of composite mechanically fastened joints is identified as a result of this review.

“…The effective properties of the composite usually depend on the average stresses or strains in the phases. However, an analytical micromechanical damage analysis should properly take into account the detailed microstructure, the spatial deformation fields, existing defects, criteria for microfailure and its evolution, and the way different defects and modes of failure interact as loading progresses [1]. This paper draws together the results from the " World-Wide Failure Exercise" (WWFE), coordinated by Hinton et.al.…”

Abstract-Different failure theories are used to assess failure analysis of composite materials as Failure criteria is important step of failure analysis. As composites material are orthotropic or anisotropic by nature so shows complex failure .There are many modes of failure such as basically fibre failure, matrix failure, inter fibre failure crack propagation, delaminations. In this we compare five theory such as Tsai , Puck, Rotem, Zinoviev and Edge there failure mode and approach used.In this we reviewed paper of WWFE by Hinton in 2002 for comparing the theories. This paper aims to solve basic problem associated with use of failure criterion for composite material.
