1 STRUCUTRAL ANALYSIS AND LIFE EXTENSION OF MINING AND PORT INFRASTRUCTURE Solution Brief

2 INDUSTRY CHALLENGE Engineers who work with the heavy machinery used in ports and mines to load and unload cargo -- and the companies that own these machines -- are well aware of the premature failures that these structures are exposed to during operations. Engineers and owners often turn to Finite Element Analysis (FEA) to guide them in making assetmanagement decisions about, for example, throughput optimization, machine repair and life assessment. But FEA has some significant drawbacks when it s used to make important decisions about large and complex machines, such as shiploaders and cranes. FEA doesn t support global system models at a level that accurately reflects physical processes acting on the structures. Instead, engineers have to either use a global coarse FEA model, which simplifies the structural detail considerably, or local fine FEA models, which don t accurately capture cumulative effects occurring within the global model. This leads to inaccurate understanding of the causes of failure and the inability to recommend proper repair procedures. AKSELOS SOLUTION Akselos Integra, the world s leading engineering simulation platform, overcomes FEA s shortcomings, providing the same results as FEA simulations and analyses, but around 1,000 times faster. Akselos Integra supports structural analysis applications that cover the entire lifecycle, from the design to the operation phase, and to eventual decommissioning. These analyses give engineers the results they need to create safe designs and to assess the strength of their structures at the speed of thought. Regardless of the complexity of your structures, Akselos Integra ensures more realistic modeling than ever before. With Akselos Integra, you gain a deeper confidence in your designs and ensure structural integrity of your most critical assets. BENEFITS Reduce OpEx costs by optimizing repair strategies and extending inspection intervals. Gain a deeper understanding of the operating margins and an increased confidence in the company s readiness and contingency plans for the unexpected Accurately estimate the remaining useful life of an asset with a global condition-based model that takes into account cumulative damage in the entire structure. The key is that Akselos uses the Reduced Basis (RB) method that, at its core, closely resembles FEA but allows for faster solve times while using much less computer power. Companies in the mining, offshore, and wind energy industries use Akselos Integra to solve their most demanding engineering problems while reducing costs and inefficiencies and gaining a competitive advantage.

3 Component-based model of a shiploader structure. MODELING Component-based modeling Akselos Integra offers a unique component-based modeling method with which engineers can efficiently construct large, reusable, and reconfigurable models from smaller, parametrized components. This componentbased modeling approach lets engineers quickly create custom model configurations by changing the parameters of individual components to support different analysis scenarios. This results in a powerful interface to perform trade-off studies and contingency planning quickly and efficiently. Engineers use this component-based modeling approach to create large high-fidelity models that include beam, shell, and solid elements without incurring huge computational costs. This means that we can use the right level of modeling detail to serve engineering needs, without being restricted by the computational limitations imposed by FEA. Condition-based modeling With Akselos Integra, you can quickly produce the most challenging 3D models of existing conditions for an entire structure. You can reliably build a fully detailed 3D model in less time than if you used conventional FEA tools and without risks of software limitations. This enables you to capture the structure s exact condition by incorporating real-life data, such as corrosion, damage and cracks, within a global finite element model. Parametric Akselos models enable crack geometry to be updated in seconds speeding up analysis and studies. Akselos Integra also supports script-based (using Python) post-processing of key quantities, such as J-integrals on crack tips to assess and predict crack propagation. These features enable you to incorporate all inspection data into a true condition-based model to perform accurate life assessment and risk analysis of critical machines in their present state, as opposed to an idealized pristine state.

4 Nonlinear In addition to providing linear analysis capabilities, Akselos Hybrid Solver enables fast analysis for the full range of nonlinear behavior (e.g. nonlinear geometry, contact, plasticity) within large and complex structures. The Hybrid Solver uses FEA components in nonlinear regions in conjunction with RB-FEA components in linear regions for a best of both worlds approach to nonlinear analysis. The Hybrid Solver allows for the accuracy and flexibility of FEA for nonlinear analysis and still brings RB-FEA acceleration to regions of the model in which there is no nonlinear behavior.

Wide range of load types Understanding the performance under combined load conditions is essential to analyzing the structures response. With Akselos Integra, engineers can assess the response of the structure under different environmental loading conditions for static and time domain. This includes self-weight loads, liveloads while the asset is in operation and wind loads. ADVANCED ANALYSIS Linear Akselos RB-FEA solver is ideal for solving static, dynamic, and modal linear analysis of large-scale structures at a 1000x speedup compared to standard FEA. This enables engineers to produce detailed stress analysis reports of thousands of load cases and load combinations to improve structural design integrity and ensure reliable and safe designs. Automated analysis generation Decision Support System is a powerful tool within the Akselos Integra platform that provides engineers with a holistic view of the model s strength and stability for different loading conditions, at once. Build around a fully detailed 3D model of the structure, the Akselos Decision Support tool allows unit managers to instantly see the results of inspections, forecast the condition of any piece of the asset, and carry out risk analysis. The tool can also be used to automate code-based analyses and the analysis of a large number of load cases, and generate reports that summarize critical issues. Results are displayed on the model so users can see which specific components are over-strength or under-strength based on predefined tolerances. This is an immense time saving tool that aids engineers in assessing the reliability of their designs and assets quickly and efficiently. As a leading engineering simulation platform, the Akselos Integra platform and its Akselos RB-FEA Solver revolutionize asset management and enable you to understand and manage structural safety risk for your entire asset more effectively than anything else on the market.
