Analysis of A Composite Time Integration Scheme

Submitted by sandeep@kaiser… on

This paper proposes a simple extension to a collocation based composite time integration proposed by Silva and Bezerra. In this scheme, each time step is further divided into two substeps which may not be necessarily equal. In the first substep, the Newmark scheme is employed and the three point backward Euler scheme is used in the second substep. Stability analysis of the scheme is performed and spectral radius, period elongation, and amplitude decay are discussed. The influence of Newmark parameters and substep sizes on stability and accuracy is studied in detail.

MIT Faculty Positions in Civil and Environmental Engineering

Submitted by Markus J. Buehler on

The Department of Civil and Environmental Engineering (CEE) invites applications for several tenure-track faculty positions to begin July 2016 or thereafter. Appointments will be at the assistant or untenured associate professor level. In special cases, a senior faculty appointment may be possible.  We will consider exceptional candidates in all areas related to Civil and Environmental Engineering.  Further information about the department can be found at http://cee.mit.edu/about-mit-cee.

Submitted by unnithan on

The Department of Aerospace Engineering & Mechanics (AEM) at The University of Alabama invites applications for a tenure-track faculty position in areas related to space and astronautics. It is anticipated that the successful candidate will join the faculty at the rank of tenure-track Assistant Professor, although exceptional candidates may be considered for higher rank depending upon experience and qualifications.

How can I generate an inp file without running the job using python scripts?

Submitted by Angela Lemos on

Hello there. I am trying to modify the INP file of abaqus and for that I need to generate the INP file before running my model. In Abaqus CAE that is possible by simply clicking with the right button on the created job and selecting the "write input" option. However I don't know the code to order the same in my script. Can anyone help with this?

The Weak Compatibility Equations of Nonlinear Elasticity and the Insufficiency of the Hadamard Jump Condition for Non-Simply Connected Bodies

Submitted by arash_yavari on

We derive the compatibility equations of L2 displacement gradients on non-simply-connected bodies. These compatibility equations are useful for non-smooth strains such as those associated with deformations of multi-phase materials. As an application of these compatibility equations, we study some configurations of different phases around a hole and show that, in general, the classical Hadamard jump condition is not a sufficient compatibility condition.
