Structural Analysis
Structural testing and analysis is a basic requirement for engineers in every industry. In fact, the use of FEA for structural analysis has become so commonplace that some suggest it is “commodity technology” that can be selected on the basis of price. Smart engineering and CAE managers, however, are recognizing that price and cost are not synonymous. Choosing structural analysis solutions that can grow with your evolving needs, rather than become obsolete, leads to lower overall cost of ownership and the difference between a costly mistake and an achievement to be proud of.

MSC.Software provides a family of high performance solutions for structural FEA that meet the needs of beginning engineers and designers, experienced experts, and everyone in between. These solutions help companies meet their business challenges by helping engineers to develop deeper insight in their products through virtual testing. Engineers using MSC structural analysis are able to evaluate many different types of designs, giving high confidence that the final design will successfully meet prescribed requirements, before the physical product is built. From single components to large complex systems, from linear static to highly non-linear dynamic problems, MSCs structural analysis capabilities are built to grow with your business, optimize your cost of ownership, and support you in achieving your goals.

Analysis Types
Product operating conditions and functional requirements dictate the type of analysis that needs to be performed on a structural component or system. Often, these solution types require a specialized type of simulation technique to provide accurate, efficient and fast simulations, and most products will have structural requirements in multiple categories.

Primary simulation types include:
  • Linear and nonlinear analysis
  • Static and dynamic analysis
  • Buckling analysis
  • Steady state, transient, frequency response, modal, and acoustic analysis
  • Multiphysics and multidiscipline analysis
  • High velocity and impact analysis
  • Damage, Failure, and wear analysis
MSC has been developing and delivering leading solution technologies in all of these key areas for over 40 years, often being driven by the most advanced needs for aerospace and automotive vehicle development. Since the fundamental engineering and design principles are common across products from many different industries, everyone can benefit from the proven capabilities available in Our structural analysis solutions.

Optimization and Design Improvement
During the design and development stage of the Product Development (PD) process, the goal is to identify the best design to meet a number of different requirements. This requires the ability to identify the feasible design space, and then to develop the best or optimum design. MSC offers solutions to help address design improvement and optimization through gradient based shape, size and topology techniques for structural component or systems and multi-run techniques to help understand the global behavior of a design, giving confidence that a robust design is delivered.

Multidiscipline, Coupled and Chained Simulations
Obtaining correct loading and boundary conditions for a structural simulation can be challenging. The quality of the result of a simulation is directly related to the quality of the inputs. When it is difficult to obtain good loads and boundary conditions it is often best to rely on other CAE simulations to generate that information. This is where multidiscipline, coupled and chained simulations can both simplify the process of re-using simulation data, and improve the overall simulation fidelity, which in turn improves the quality of and confidence in the simulation.

Here are some examples of how Our solutions can improve your simulation capabilities:
  • Motion-Structure Integration:
    • Can improve the simulation quality by providing more accurate loading data obtained from a multibody dynamics simulation – chassis and suspension loads applied to the vehicle structure – aircrafts, automobiles, washing machines
    • Provide more efficient stress predictions by using flexible bodies in a multibody dynamics simulation; vehicle and aircraft frame/structure fatigue, fatigue life of the read/write heads on a computer hard disk drive
  • Coupled thermal-structural analysis can give more accurate stress results when accounting for both the thermal loads and the structural loads simultaneously - combined friction and pressure loading of brake disk and rotor
  • Fluid-Structure Interaction (FSI)- coupled solution provides more accurate fluid flow simulation when deformed structure is considered, and structure loading is more correctly applied on affected surfaces – tire hydroplaning; airbag deployment; blood flow over an artificial valve
  • Chained structural simulations will provide more accurate analysis for example by applying pre-loads/pre-stress before event simulation – aircraft engine blade-out simulation; automotive engine modal analysise, Failure, and wear analysis
