Devers Eye Institute uses MSC Patran for FE Modeling to Study Glaucoma
Glaucoma is the second leading cause of blindness in the US and is usually associated with elevated intraocular pressure (IOP). The principal site of glaucomatous damage is believed to be within the optic nerve head (ONH) where the retinal ganglion cell axons pass through an opening in the back of the eye wall on their path to the brain. This opening, known as the scleral canal, is spanned by the lamina cribrosa,...

WPI uses Patran to Create Complex Models in Roadside Safety
The Roadside Safety Research Group at Worcester Polytechnic Institute (WPI) has been modeling crash events and, in particular, full-scale crash tests for many years under the guidance of Prof. Malcolm H. Ray. With the latest generation of explicit non-linear Finite Element solvers is now possible to simulate a complex event such as a crash test or an impact in general in a very realistic detail. This allows the researcher t...

ASU teaches Structural Dynamics with Nastran
In the Fall, I was teaching the graduate Advanced Structural Dynamics class to a group of graduate students, both full time students and part time ones from local companies. A sizable part of the course focused on "component modal synthesis" methods for the modeling of complex structures composed of multiple components. I usually cover 4 different methods. The first two methods rely on free boundary modes, either alone (the "naive" method...

University of Virginia Uses Adams for Modeling and Simulation of the Vertical Climber
The human musculoskeletal system is configured primarily for stable and efficient locomotion based on bipedal gait patterns. However we are often tasked with motion or postures for which the body is optimized. One such activity which is growing in popularity is rock climbing. Climbing can be distinguished from other types of locomotion in two ways. Most obviously climbing represents vertical motion...

University of Pittsburgh uses MD Adams with LifeMOD to estimate muscle forces during drop-landing and stop-jump tasks
The Neuromuscular Research Laboratory (NMRL) at the University of Pittsburgh has conducted research to study comprehensive profiles of an individual’s function by evaluating both the sensory and motor characteristics specific to musculoskeletal injury and pathology. Biomechanical and neuromuscular assessments in sports-simulated environments are used to determi...

École Polytechnique uses MSC Adams to model spinal deformities
Introduction: Scoliosis is a complex deformity of the spine affecting 3-4% of the children, which needs a surgical intervention in severe cases. There is currently no clinical tool sufficiently user-friendly, reliable and refined for the preoperative planning and prediction of correction using different instrumentation configurations. Our objectives were to develop a "spine surgery simulator" for ...

University of Toledo uses MD Nastran for Probabilistic Vibration Analysis
Car manufacturers must design cars with low noise and vibration in order to succeed in today’s competitive market. For this purpose, they need accurate and efficient computer programs to assess noise and vibration of many alternative designs. Car designers perform repeated finite-element analyses of very detailed finite element models to determine their performance. ...

PROTON can shorten the time-to-market by getting designs right the first time
In developing complex mechanical and structural automotive components, going through multiple build-and-test hardware prototype cycles to verify performance, stress and fatigue life is just too time-consuming and expensive. This issue can be addressed by evaluating and refining designs with analysis tools up front in development, reducing test cycles later in the development process. PROTON's pioneering sp...

University of Houston uses Patran for computational-mechanics modeling of Gas Turbine Shaft
In an aero-derivative gas turbine, rapid airflow-induced loading acts on the valve disk, causing dynamic motion of the system. In various operational conditions, the shaft (with a keyway) transfers the aerodynamic torque acting on valve to pinion and rack gears. Stress concentrations in the keyway under the aerodynamic load are found to depend on: (1) keyway size and geometry, (2) shaf...

Texas A&M uses Patran for Analysis on Stent Design
Vascular stents are a medical device designed to restore blood flow to constricted arteries (e.g. atherosclerotic lesion). Stents have become a standard for treating atherosclerosis due to distinct advantages in trauma and cost with other surgical techniques. Unfortunately, the therapy is hindered by the risk of a new blockage (restenosis) developing in the treated artery. It has been hypothesized that stent-induced chang...

University of Aarhus used MD.Nastran to assess methods for fastener modelling in cooperation with Terma A/S
In the aeronautical industry, mechanical fasteners still remain as the common method for bonding parts, to avoid crack propagations and uncertainties of threaded holes and welded joints respectively. Due to this, an exact representation of fasteners are needed for implementing these in FE analysis, which is done differently by different companies. In that context, the U...
