Compressive performance of MAX phase composites

Compressive performance and crack propagation in MAX phase composites 


Here micro CT was used to reveal the structure performance relationships in metal/ceramic composites based on Ti2AlC / Al alloy combinations.

The results show the promise of infiltrated max phase materials in the production of high performance composites.

Temperature induced crack propagation in structured media

This paper describes the propagation of an edge crack in a semi-infinite triangular lattice, consisting of identical point masses connected by thermoelastic links. A change of temperature, represented by a time-periodic series of high-gradient temperature pulses, is applied at the boundary of the lattice. In order to make the initial crack advance in the lattice a failure criterion is imposed, whereby the links break as soon as they attain a prescribed elongation.

Numerical analysis of quasi-static fracture in functionally graded materials

This work investigates the existing capabilities and limitations in numerical modeling of fracture problems in functionally graded materials (FGMs) by means of the well-known finite element code ABAQUS. Quasi-static crack initiation and growth in planar FGMs is evaluated. Computational results of fracture parameters are compared to experimental results and good agreement is obtained. The importance of the numerical fit of the elastic properties in the FE model is analyzed in depth by means of a sensitivity study and a novel method is presented.

Postdoc position — Modeling fragmentation in brittle materials

Hopkins Extreme Materials Institute (HEMI; of The Johns Hopkins University is seeking a Postdoctoral Fellow to work on modeling fragmentation in brittle materials under extreme loading conditions. The potential candidate should have a Ph.D., with some background in fracture mechanics and experience working with the finite element or some other numerical method.

Modelling fracture of graphene using Griffith’s criterion and quantized fracture mechanics

In armchair graphene sheets, crack propagates perpendicular to the applied strain, whereas crack propagation in zigzag sheets occurs at an angle to the straining direction. This occurs due to different bond structure along armchair and zigzag directions as shown in Fig. 1. Videos 1 and 2 show the fracture of armchair and zigzag sheets, respectively.

criterion to stop crack analysis in xfem

Dear all,

my problem is dealing with a fatigue crack propagation analysis using XFEM (linear elastic case) with a prescribed initial imperfection in the modeled solid. What is the criterion to exit from such a kind of analysis?

Thank you in acvance!

Crack Propagation by Cohesive Element

Hi everyone,

 I've been working on crack propagation problem by cohesive elements in Abaqus.

 I have a sandwich struture where adhesive bonds two steels together. And I've attached part of my input file in the following.

 I can have the stress and strain distribution, but I really expect the crack will propagate in the midplane of the adhesives. I don't know whether I have to preset a line in the middle of adhesive as existing crac, or I can set some crack interaction to get the crack growth result. 

Open Position in Computation Solid Mechanics

Position: Computational Solid Mechanics Research Engineer

Company: Global Engineering Research and Technologies (GERT)

Location: Tucson, Arizona, USA 

Full/Part time: Full Time. 

Benefits: Yes.

Salary: Commensurate with Qualifications.

Remote employment: No. Must be willing to relocate to Tucson, AZ.

Cohesive Zone and Cohesive Element

Hi all,

I had been trying to reproduce a crack propagation problem using XFEM/Cohesive Zone. The problem is a 200x200x50 notched plate which has been simulated using plane strain elements 200x200 with 50 mm thickness.

I generated the cohesive layer (zero thickness) between the plane strain elements in the notch region, as cohesive elements and cohesive material properties which will define the crack initiation location.

Crack problems in A380 and BOEING 787

A point in which I may contribute from my oint of view is the crack problrem because of asymmetric bending

or because of the "off axis" bending. It is a problem in which I am working with Professor Sideridis at this time in National Technical University of Athens.


how to do a crack propagation analysis?

can abaqus be used for doing crack propagation analysis for plates with multiple cracks?

Crack propagation in ductile materials under monotonic loading

Hello everyone;

 I am Msc student and work on simulation of repairing the cracked steel girders using CFRP in abaqus.

I induce a geometrical crack in steel beam model and exepct it propagate in failure strain path, after increasing the load

I  have a question about crack propagation of steel girder under monotonic loading, what criterion of fracture is suitable for this case?
