Job description
In the latest volume of Engineering Fracture Mechanics there is an interesting paper about the calculation of crack growth paths by use of a phase field model. The considered material is inhomogeneous and that causes the crack to follow a winding path through the material. The material structure is from a CT scanned micro-structure of a cement-based porous material. The paper is:
Case study: Cyberwood
I'm doing my master degree on fracture mechanics
I want to simulate crack propagation direction on the basis of strain energy density fracture criterion (SED) under mixed loading
I'm using abaqus program but i dont know how to do this
so please if you can help me to know if the program can do this and how
Article title: Microstructural evolution in bitaxial crack-seal veins: A phase-field study
We numerically investigate the characteristics of concurrent carbon redistribution pathways, as the ferrite–austenite front evolves during an isothermal eutectoid transformation starting from a random distribution of preexisting cementite particle. By analyzing the influence of initial interparticle spacing, arrangement and undercooling (below A1 temperature) on the curvature-driven coarsening, we generalize the present criteria of non-cooperative eutectoid transformation.
A state of stress in a body. Components of stress. Subject to a load, a body develops internal forces. The distribution of the internal forces in the body is usually inhomogeneous. For example, when a rod is bent, part of the rod is in tension, and the other part of the rod is in compression.
If the internal forces are uniformly distributed in the body, the body is said to be in a homogeneous state of stress. For brevity, we often say a state of stress, or just stress.
Subject to compression, elastic materials may undergo bifurcation of various kinds. A homogeneous material forms creases, whereas a bilayer consisting of a stiff film and a compliant substrate forms wrinkles. Here, we show several new types of bifurcation behavior for bilayers consisting of films and substrates of comparable elastic moduli. Depending on the ratios of moduli and thicknesses of the two materials, the critical strain for the onset of creases can be either smaller or larger than that for the onset of wrinkles.
