Software Development

APTEK has continually developed innovative, custom software for both commercial and research & development purposes.  Much of the software developed was used to assist the many engineering studies that APTEK has conducted throughout our history. Other software was developed to meet specific customer needs. For approximately 6 years we developed Graphical User Interface (GUI) codes for NASA to assist in optimized packing of items and for inventory management. The NASA work resulted in U.S. Patent #5950190, Dynamic, self-modifying graphical user interface for use with relational databases.

Material models that we developed for use in finite element structural response codes to describe the non-linear behavior of reinforced concrete, wood and soil have been incorporated into the commercially available structural response code LS-DYNA, available from Livermore Software Technology Corporation.

Commercial

Mixed Mode Constitutive Driver (MMCD)

The Mixed Mode Constitutive Driver (MMCD) is a new graphical software package that helps the user to efficiently evaluate the response of material models implemented in the LS-DYNA finite element code, and to fit the material model parameters to test data (parameter identification).   APTEK leases copies of the Mixed Mode Constitutive Driver (MMCD) on a commercial basis using this web site.

Thermo-Structural Response Toolkit (TSRTk)

APTEK developed the Thermo-Structural Response Toolkit (TSRTk) for the Defense Threat Reduction Agency. TSRTk is used to predict the response of missile system components subjected to intense x-ray loads. It is available to government approved entities.

Composite Retrofit Program

The Composite Retrofit Program (CRP) is a web-based program for predicting building component vulnerability and retrofit selection. Building components include reinforced concrete columns and beams, and walls made of concrete masonry units. Vulnerability is reported as level of damage (none, slight, moderate, severe). Threats are terrorist bomb attacks with uncased charges for a variety of explosives (like TNT or C4) and standoffs (5 to 200 feet). Retrofit options include composite materials (carbon/epoxy, Kevlar/epoxy, and fiberglass) for wrapped columns, plated beams, and fabric-backed walls.

This program is available for lease from APTEK.
