Finite Element Modeling of Brittle and Ductile Modes in Cutting of 3C-SiC
Crystals, 2021 Machining of brittle ceramics is a challenging task because the requirements on the cutting tools are extremely high and the quality of the machined surface strongly depends on the chosen process parameters.

Progressive damage and rupture in polymers
, 2017 Progressive damage, which eventually leads to failure, is ubiquitous in biological and synthetic polymers. The simplest case to consider is that of elastomeric materials, which can undergo large reversible deformations with negligible rate dependence. In

Evaluation of volumetric strain quantities and types of volumetric strain curves under failure-deformation process of hard brittle rocks [PDF]
, 2018 Purpose. The aim of this work is to show whether or not a relationship exist among the different volumetric strain quantities and to assess also whether the volumetric quantities are related to the different types of volumetric strain curves under ...

, 2002 We suggest that the observed large-scale universal roughness of brittle fracture surfaces is due to the fracture process being a correlated percolation process in a self-generated quadratic damage gradient.

High-accuracy phase-field models for brittle fracture based on a new family of degradation functions [PDF]
, 2017 Phase-field approaches to fracture based on energy minimization principles have been rapidly gaining popularity in recent years, and are particularly well-suited for simulating crack initiation and growth in complex fracture networks.

Damage Constitutive Model of Microcrack Rock under Tension
Advances in Civil Engineering, 2020 To investigate the tensile properties of brittle rock with microdamage, an indirect tensile test was conducted. High-speed image acquisition and acoustic emission (AE) were applied to record the process.

Analysis of Corrosion-Fatigue Damage and Fracture Mechanism of In-Service Bridge Cables/Hangers
Advances in Civil Engineering, 2021 Cables/hangers are important load-bearing components of suspension, cable-stayed, and through-arch bridges. Their reliability throughout their service life directly affects the safety of these bridges. In this study, to provide a reference for the design,

Beam-Induced Damage Mechanisms and their Calculation [PDF]
, 2016 The rapid interaction of highly energetic particle beams with matter induces dynamic responses in the impacted component. If the beam pulse is sufficiently intense, extreme conditions can be reached, such as very high pressures, changes of material ...
