Fracture toughness is equal to fracture energy in LEFM?
Hi,
I am doing some test on the fracture toughness.
I am wondering if in Linear Elastic Fracture Mechanics, Fracture toughness of the material is equal to fracture energy or not?
Can anybody send me an naswer,
Thank you,

Pyramid elements in ABAQUS
Hi every body,
I need to generate a mesh around the crack front line in 3-dimensional space using a layer of prism (wedge) elements at the crack line and tetrahedron elements at the rest parts of the model. However, to keep the compatibility we also need to adopt a layer of pyramid elements between wedge elements and the tetrahedrons. Dose any body know how can I do that in ABAQUS? Is pyramid element available in ABAQUS's element library or is there any chance to get that through degenerating another element type? if so, how?
Metal Infused Cellular Materials
Any suggestions regarding papers on metal-infused cellular materials? E.g., aluminum or aluminum metal-matrix composite infused into open cell titanium with millimeter scale pores?

Trouble with linear elastic theory of strength
A body is subject to a load. What is the magnitude of the load that will cause the body to fracture? Let us begin with a body made of a glass, which deforms elastically by small strains. A procedure you have been taught before probably goes as follows. You first determine the maximum stress in the body. You then determine the strength of the material. The body is supposed to fracture when the maximum stress in the body reaches the strength of the material.
