Interference Stress/Strength Analysis
In simplest terms, an item fails when a stress to which it is subjected exceeds the corresponding strength. In this sense, strength can be viewed as “resistance to failure.” Good design practice is such that the strength is always greater than the expected stress. The safety factor “η” can be defined in terms… Read More
Derating
Introduction
A brief overview of the importance of derating has been provided here, along with a sample determination of requirements calculations using Quanterion’s QuART-ER derating calculator and a description of the Stress-Derating Spreadsheet Calculator – SD-18. This topic is also covered in the Quanterion-authored Reliability Information Analysis Center (RIAC) publication “System Reliability Toolkit” and is included… Read More
Quanterion Solutions Incorporated, a Utica/Rome–based small technology business headquartered at the SUNY Polytechnic Institute (SUNY Poly), is growing based on several recent contract awards:
Quanterion is a team member of two DoD Multiple Award Contracts (MACs), the Homeland Defense Technical Area Tasks (HD TATs) and the Defense Systems Technical Area Tasks (DS TATs). Under subcontract to MacAulay-Brown… Read More
Quanterion Solutions’ Stress-Derating Spreadsheet Calculator – SD-18 Derating Standard is an Excel-based software tool that allows the user to easily determine if a design is in compliance with the derating guidelines presented in NAVSEA SD-18 Part Requirement and Application Guide. After selecting the application environment and entering the ambient baseline temperature, the user then enters… Read More

Quanterion has released the “Handbook of Software Reliability and Security Testing,” a comprehensive manual developed for the DoD’s Cyber Security and Information Systems Information Analysis Center (CSIAC).
The increasing complexity of modern systems, and systems-of-systems, is such that reliability considerations must extend beyond hardware, and include both software and human-machine interactions. This book specifically addresses software… Read More
Models Commonly Used to Measure Reliability Growth
Reliability growth is the intentional positive improvement that is made in the reliability of a product or system as defects are detected, analyzed for root cause, and removed. The process of defect removal can be ad hoc, as they are discovered during design and development, a function of an… Read More
