While NASGRO is a widely used software tool for fracture simulation it is limited to the simple geometrics included in its library. The interface to NASGRO available in BEASY enables you to build upon the NASGRO capabilities to predict crack growth in more realistic and complex structures whilst continuing to use the NASGRO crack growth laws and materials data.

BEASY’s Fracture & Fatigue Crack Growth (FCG) software enables engineers to quickly develop high fidelity fracture mechanics models based on the actual structural component geometry and loading, therefore providing more accurate critically important data on stress intensity factors, crack growth and crack shape evolution.

Benefits

• Easily move from NASGRO reference book solutions to more realistic geometry and loading
• Uses a mixed mode stress intensity factor solution (KI, KII, KIII) to simulate accurate, nonplanar, crack shape evolution (not restricted to Mode 1 solutions)
• Predict SIFs and fatigue crack growth under complex multiaxial loading
• Support for multiple cracks and coplanar crack coalescence
• Simulate crack growth in residual stress fields

Predicting the Impact of Hydrogen on Cracks

With the recent interest in the use of Hydrogen as an alternative fuel and the issues regarding its distribution, in this issue we are reviewing the results of a research project in which BEASY engineers investigated the impact of hydrogen on the integrity of gas transmission pipelines.

Software was developed to predict how adding hydrogen to the natural gas distribution network would affect the probability of failure. Hydrogen has been demonstrated to change the behaviour of crack like defects which may affect the safety of pipeline or make it more expensive to operate.

A stochastic approach was developed to assess the failure probability of the gas pipeline due to the existence of crack-lie defects including the operational aspects of the pipeline such as inspection and repair procedures. With various parameters such as crack sizes, material properties, internal pressure modelled as uncertainties, a reliability analysis based on failure assessment diagram was performed through direct Monte Carlo simulation.

The failure probabilities of each defect and the whole pipeline system were obtained from the simulation and different inspection and repair criteria were investigated to determine an optimal maintenance strategy.

NEW PRODUCTS & SERVICES TO BE PRESENTED AT AA&S 2019

BEASY Model Cutting Tool

The BEASY model cutting tool is an "add on" feature to further simplify the creation of BEASY fracture and crack growth simulation models from FEM models such as NASTRAN, ABAQUS, ANSYS, PATRAN etc

 
BEASY Fracture Assessment Tool

BEASY Fracture Assessment Tool (BEASY FASST) can be used to quickly assess the impact of a crack on the structural integrity of a structure. The tool can be used with FEM or BEASY models to predict how stress the intensity factor (SIF) varies with crack size for a crack located at any position on the model. This can be used as a fast assessment tool before a full scale simulation is performed.

BEASY POLCURVEX

BEASY POLCURVEX software is used by design engineers to quickly assess the corrosion risk of material combinations exposed to aqueous environments.

BEASY Polarisation & Corrosion Rate Prediction

BEASY POLCURVEX software is used by design engineers to quickly assess the corrosion risk of material combinations exposed to aqueous environments. Galvanic corrosion is one of the primary, and most costly, corrosion mechanisms observed when different metals and finishes are coupled. BEASY POLCURVEX provides a more accurate, laboratory validated, method to predict corrosion rates based on the identification of crossing points for material polarization curves.
Galvanic corrosion is commonly assessed by comparing differences in metal potential (e.g. galvanic series in seawater table) with higher corrosion risk being associated with larger differences in metal potential. However recent research results obtained during development of the revised military standard, MIL-STD-889C suggests that potential differences do not fully account for the corrosion kinetics and can lead to wrong material compatibility decisions.
Given the high cost of corrosion maintenance many companies are searching for corrosion modeling tools to support the paradigm shift from “Find & Fix” to “Predict & Prevent/Manage”. The BEASY POLCURVEX software provides critical information to designers, focused on metal compatibility and coating performance of new designs and retrofits and maintenance engineers concerned with scheduling inspections to look for corrosion.
