In this paper, crack growth analyses on composite panels containing embedded delaminations has been performed using the geometrically non linear FEM code B2000, based on the Total Lagrangian Formulation. The code has been improved with an effective Virtual Crack Closure Technique to evaluate Energy Release Rate and with Penalty Method to evaluate contact forces. Validation of the proposed tool has been performed with experimental and numerical data available in bibliography for Double Cantilever Beam specimens and panels with embedded delaminations.

Abstract
In this paper, crack growth analyses on composite panels containing embedded delaminations has been performed using the geometrically non linear FEM code B2000, based on the Total Lagrangian Formulation. The code has been improved with an effective Virtual Crack Closure Technique to evaluate Energy Release Rate and with Penalty Method to evaluate contact forces. Validation of the proposed tool has been performed with experimental and numerical data available in bibliography for Double Cantilever Beam specimens and panels with embedded delaminations.File in questo prodotto:
