Learn More About RadiossCrash and Safety
Radioss is a recognized solution for crash testing, safety analysis, and vehicle design optimization. To ensure transportation methods meet ever-stringent safety standards, Radioss' advanced solver technology enables engineers to simulate complex scenarios such as full-vehicle crash, high-speed impacts, and vehicle rollovers. Radioss supports the broader industry shift toward electrification with dedicated material and failure models for detailed analysis of applications like battery systems for electric vehicles (EVs) and urban air mobility concepts (UAM).
High Velocity and Dynamic Event Analysis
Crucial for ensuring the safety and reliability of large-scale components, Radioss enables accurate simulation of extreme events such as bird strikes, jet engine blade containment, and structural failures. Radioss offers a range of composite material models that are used to ensure performance and efficiency. Validated models for high-impact scenarios, such as bird models, help engineers design for safety and reliability for critical applications such as aircraft windshields and engines.
Blast and Ballistic Analysis
Originally developed to address the extreme load cases found in defense applications, Radioss has evolved into a versatile solution for simulating high-energy events. From blast analysis to ballistic impacts, Radioss helps engineers design safer, more resilient protective systems. With advanced techniques such as the Arbitrary Lagrangian-Eulerian (ALE) method and smoothed-particle hydrodynamics (SPH), Radioss enables accurate simulation of complex interactions in scenarios for protective systems and equipment and critical infrastructure.

Renewable and Sustainable Energy
Radioss enables the design and validation of energy systems that must perform reliably under harsh environmental and operational conditions. Engineers can simulate seismic activity and other large, sudden forces that influence the safety and longevity of energy infrastructure. To address climate-driven risks, Radioss also supports detailed simulation of scenarios such as hailstone impacts, helping improve the resilience of components like solar panel surfaces.
Drop and Impact Testing
Radioss helps engineers enhance the performance and reliability of complex devices by simulating real-world scenarios such as drop tests, impacts, and misuse. These insights enable teams to assess how components like screens, batteries, product casings, and their packaging will behave under shock before physical prototypes are built.
Using advanced material modeling and structural analysis, Radioss also supports the simulation of fabrics, rubbers, and foams to ensure products are durable, comfortable, meet user expectations, and help reduce injury risk.
Material Performance and Fluid-Structure Interaction
Simulating how complex materials behave and interact with fluids under dynamic conditions is critical for designing high-performance systems. Radioss enables detailed analysis of complex nonlinear material behavior, large deformations, and fluid-structure interactions (FSI) to improve safety, reliability, and functionality. These capabilities support a wide range of applications—from bespoke medical and wearable devices to systems where soft materials and fluid dynamics play a key role.

Safety System Simulation with MADYMO-Radioss
The Webinar will outline how engineers can combine the best of both worlds in a single co-simulation environment and gain considerable time saving in vehicle developments. The Radioss-MADYMO coupling solution enables engineers to use the same MADYMO dummy and restraint models in occupant safety analysis as well as in the RADIOSS structural analysis. This removes the need to create intermediate FE models of the restraint system, which reduces development time and provides higher confidence in simulation results.
