Computational Models for Ductile Fracture Prediction in Jan 01, 2014 · The performance of these models is evaluated using experimental data, and the merits and limitations of these models are provided. Finally, a new computational failure locus model is proposed and is used as a fracture criterion in ABAQUS ® finite element software to predict the ductile fracture in ASTM A992 structural steels.
Cumulative Damage Analysis - SlideShareApr 28, 2016 · Literature Review Cumulative Damage Analysis Kieran J. Claffey 23 The value of the fracture toughness on the K1 (fracture toughness) axis occurs when the slope of figure 3.14 goes to infinity. 3.7.5 Life Prediction using LEFM Paris's Law, [da / dN = C ( K )n ] can be solved to yield a life prediction, once the initial crack length ai and
May 21, 2015 · This paper proposes a method to predict the thermal ageing effect on fracture toughness of CF8M cast stainless steel. The proposed method is based on multiaxial fracture strain combined with finite element
Fracture characterization of short glass fiber reinforced Jan 01, 1988 · Fracture characterization of short glass fiber reinforced polyester 267 slow crack growth after crack initiation than the specimens in the mode I fracture test and most test specimens showed catastrophic failure at their maximum loads. The strain energy absorbed up to the crack initiation point and obtained by the locus method is shown in Fig. 5.

Franco Concli was born in Bolzano, Italy, on May 21, 1985. He received his Master of Science Degree in Mechanical Engineering in 2009 at Politecnico di Milano, Italy. He developed his MD thesis about structural damages of helicopter gearboxes (Agusta-Westland). He graduated Ph.D. (European Label, with merit) on March 27, 2013 at Politecnico di Milano.
Investigation of High-Strength Steel Component Subjected The behaviour of a closed top-hat section made of Dogal 800 DP subjected to stretch-bending is studied both experimentally and numerically. The top-hat section was made by forming of a sheet using a FlexformTM fluid cell press and closed by a sheet using welding. Experiments were performed in a stretch-bending rig in two stages. During the first stage the profiles were bent under a constant
Modeling of Serrated Chip Formation in High Speed obtained from finite element simulation for three selected flat-grooved specimens Fig. 7 AISI steel 1045 fracture locus based on initial stress triaxiality, averaged using displacement limit simulation model, averaged using strain limit model, and the fracture locus based on strain at fracture. Stress triaxiality
The plasticity and ductile fracture of the present sheet are fully characterized by a Hill48 orthotropic model and a MMC fracture model, respectively. Finite element models with three different element types (3D, shell and plane strain) were built for a Stretch Forming Simulator (SFS) test (Shih and Shi, 2008), numerical simulations with
The effect of moisture on the failure locus and fracture The results provided by the test show a steady degradation in the interface fracture energy with increasing moisture content. Surface characterisation techniques such as X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) were used to
Three-dimensional finite element analysis of Nov 01, 2019 · The locus of the equivalent plastic strain to fracture proposed by Bao and Wierzbicki was used. In this model, the equivalent plastic strain to fracture, ¯ f , is described as a function of the stress triaxiality, = m / ¯ , where m is the average stress (hydrostatic tension) and ¯ is the (von Mises) equivalent stress.
