Modified compact tension specimen for experiments on cement based materials: comparison of calibration curves from 2D and 3D numerical solutions [PDF]

open access: yesFracture and Structural Integrity, 2017
The evaluation of fracture mechanics parameters of materials has become very important part of considering the condition of older constructions as well as properties of newly developed materials.

Influence of geometry, elasticity properties and boundary conditions on the Mode I purity in sandwich composites [PDF]

open access: yes, 2020
The present work addresses the problem of skin/core debonding in sandwich materials. The main goal is to carry out parametric analyses for studying the influence of various materials, geometrical parameters and boundary conditions of sandwich fracture ...

Brittle Failure of Nanoscale Notched Silicon Cantilevers: A Finite Fracture Mechanics Approach

open access: yesApplied Sciences, 2020
The present paper focuses on the Finite Fracture Mechanics (FFM) approach and verifies its applicability at the nanoscale. After the presentation of the analytical frame, the approach is verified against experimental data already published in the ...

X-FEM in isogeometric analysis for linear fracture mechanics [PDF]

open access: yes, 2011
The extended finite element method (X-FEM) has proven to be an accurate, robust method for solving problems in fracture mechanics. X-FEM has typically been used with elements using linear basis functions, although some work has been performed using ...

The effects of residual stress on elastic-plastic fracture propagation and stability

open access: yesMaterials & Design, 2018
Residual stresses in materials affect their resistance to the initiation of fracture and to subsequent crack growth. Using full-field strain measurements and finite element analysis we demonstrate that the effect of residual stress on a material's crack ...

Finite Fracture Mechanics and Cohesive Crack Model_Size effects through a unified formulation

open access: yesFracture and Structural Integrity, 2022
Finite Fracture Mechanics and Cohesive Crack Model can effectively predict the strength of plain, cracked or notched structural components, overcoming the classical drawbacks of Linear Elastic Fracture Mechanics. Aim of the present work is to investigate

Cracked finite elements proposed for NASTRAN [PDF]

open access: yes, 1973
The recent introduction of special crack-tip singularity elements, usually referred to as cracked elements, has brought the power and flexibility of the finite-element method to bear much more effectively on fracture mechanics problems.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

3D numerical modelling of twisting cracks under bending and torsion of skew notched beams [PDF]

open access: yes, 2017
The testing of mode III and mixed mode failure is every so often encountered in the dedicated literature of mechanical characterization of brittle and quasi-brittle materials.

From finite to linear elastic fracture mechanics by scaling [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2013
The authors describe the asymptotic behaviour of the propagation of a crack in a 2D brittle material. Let \(\Omega \) be a bounded, open and connected domain in \(\mathbb{R}^{2}\) whose Lipschitz boundary \(\partial \Omega \) may be decomposed as the disjoint union \(\partial _{D}(\Omega )\cup \partial _{N}(\Omega )\), with positive Hausdorff measure \(
