Conversion of a real-valued Abaqus UEL to complex-valued for the computation of first-order derivatives using the complex-variable finite element method, ZFEM. This method was developed in The University of Texas at San Antonio, UTSA and has been demonstrated for linear elastic fracture, elastic-plastic fracture, Mixed-mode loading, thermoelasticity, among others. A cantilever beam consisting o...

In this session, we covered a brief introduction to finite element modeling using Abaqus. A cantilever beam made of two materials with a concentrated force and a pressure is modeled. Geometry creation, partitions, different material sections, output requests, step definition, loads, boundary conditions and meshing techniques are covered. In addition, some post-processing and results reporting i...

In this Abaqus tutorial, the Energy Release Rate of an Infinite Array of Collinear Cracks is computed using the J-Integral. Due to the symmetry of this example, the model can be reduced to an Edge Cracked Plate with symmetry boundary conditions in the x- and y- axes. Quarter-point collapsed elements are used in the vicinity of the crack tip in order to reproduce the 1/sqrt(r) stress singularity...

Biking from Riverside Rd to Canyon Lake Dam. Beautiful view at the end of a ~10% climb to the top.

Steepest Hill that I have seen in Texas, it reaches ~ 23% at some point. My friend did not have the correct set up for this tough climb (an excuse to come back and kill it next time)

Skyline is the steepest hill climb that I have seen in Texas, it reaches 23% at some point.
