    Characterization of Elastic-Plastic Fracture Behavior in Thin Sheet Aluminum

    Composite overwrapped pressure vessels (COPVs) are used in space flight vehicles to contain pressurized gases. A COPV consists of a metallic liner to contain the gas or fluid and a composite overwrap for stren...

    A radial basis function approach in the meshless local Petrov-Galerkin method for Euler-Bernoulli beam problems

    A meshless local Petrov-Galerkin (MLPG) method that uses radial basis functions rather than generalized moving least squares (GMLS) interpolations to develop the trial functions in the study of Euler-Bernoulli...

    Review of Methods for Calculating Fracture Parameters for Interface Crack Problems

    The problem of an interface crack between two isotropic, orthotropic, or anisotropic materials has attracted attention from researchers because of applications in bonding problems involving these materials. Th...

    A Reinvestigation of Stress-Intensity Factors for Surface and Corner Cracks in Three-Dimensional Solids

    Surface and corner cracks usually initiate at imperfections and voids in metallic structures. These cracks usually grow into near or part-elliptical shapes [1]. Therefore accurate stress-intensity factors for ...

    A boundary element alternating method for two-dimensional mixed-mode fracture problems

    A boundary element alternating method (BEAM) is presented for two dimensional fracture problems. An analytical solution for arbitrary polynomial normal and tangential pressure distributions applied to the crac...

    Treatment of singularities in cracked bodies

    Three-dimensional finite-element analyses of middle-crack tension (M-T) and bend specimens subjected to mode I loadings were performed to study the stress singularity along the crack front. The specimen was mo...

    Boundary Force Method Analyses of Notched Plates with Cracks

    The Boundary Force Method (BFM), an indirect boundary element method, was formulated for two-dimensional mixed boundary value problems. The analytical solution for forces and moments applied to a cracked, infi...

    Finite-Element-Alternating Method for Analysis of Cracked Three-Dimensional Solids

    The finite-element-alternating method is used to analyze part-elliptic circumferential surface cracks in cylinders. The method showed excellent convergence characteristics and yielded accurate stress-intensity...
