I'm attempting to compile a local compliance matrix using Castigliano's theorem as described here. I'm having trouble with it and attempted to do a simple example by hand and picked the double cantilever beam specimen and analyzed it with Euler-Bernoulli beam theory (attached). Despite my best efforts, I can't reproduce the correct answer using the theorem as is but only if I modify the limits of integration.

Abstract

Fracture mechanics of shape memory alloys: review and perspectives

Submitted by Theocharis on Mon, 09/21/2015 - 02:22

finite element analysis

Shape memory alloys (SMAs) are intermetallic alloys displaying recoverable strains that can be an order of magnitude greater than in traditional alloys due to their capacity to undergo a thermal and/or stress-induced martensitic phase transformation. Since their discovery, the SMA industry has been dominated by products for biomedical applications with geometrically small feature sizes, especially endovascular stents.

The surface-forming energy release rate based fracture criterion for elastic-plastic crack propagation and interpretation on paradox of Rice

Submitted by Bin Liu on Mon, 09/07/2015 - 03:11

fracture mechanics

The J-integral based criterion is widely used in elastic-plastic fracture mechanics. However, it is not rigorously applicable when plastic unloading appears during crack propagation. One difficulty is that the energy density with plastic unloading in the J-integral cannot be defined unambiguously.

Load Displacement curve for XFEM in ABAQUS

Abaqus XFEM

ABAQUS XFEM crack propagation

I am using Maxps Damage criteria for an XFEM crack for a three point bending case. I am using displacement loading on the specimen and wish to plot reaction load v/s mouth opening displacement. I would like to know how to obtain the crack tip opening displacement in ABAQUS. All the journal papers I read show a slump in reaction force after the crack starts to propagate. I plot the results and contour plots show me clearly that the crack has started to propagate. Please help.
