Piezoelectric sensor-actuator technology is often used in high-tech industries like medical, mechanical, automotive engineering and semiconductor markets. Applications of piezo-based ultrasonic sensors range from fuel injectors, flow-rate metering, ultrasonic welding, and high-resolution material testing to medical diagnostics. A piezoelectric finite element analysis involves computation of coupled stress and electric field in certain crystalline materials. In …

Composite materials of various types (unidirectional composites, short fiber reinforced plastics, nano-composites, ceramics, etc.) exhibit highly nonlinear, anisotropic, strain-rate and temperature dependent properties in mechanical, thermal and electrical fields. They often exhibit enhanced performance with respect to density as compared to traditional structural materials. However, simulating composite structures is complicated, and usually requires a micro-mechanical, …

The reactor pressure vessels make up the heart of a nuclear power plant, containing the core, core shroud and coolant. These nuclear plants were built and started operating 20 to 30 years ago. The company operating this plants needed to know how this welds can be expected to perform after a long period of service. …

Simulation of complex manufacturing processes (like welding) needs to take phase transformations of elastoplastic materials into consideration, in order to account for the microstructural properties in the weld core and HAZ (Heat Affected Zone). Such simulations can predict peak temperatures, residual stresses and weld distortions after cooling. Welding defects like hot cracks can thus be …

Simulation and analysis, or Computer Aided Engineering (CAE), enables engineers and organizations to analyze and explore new packaging processes and methods in a virtual environment, reducing the time and cost requirements associated with physical and experimental testing. For over 40 years, product manufacturers in transportation industries have relied on computer simulations as a means to …

Engineering Simulation has become a critical, if not fundamental, part of the design and development process at all forward looking companies, big and small. Students entering the job market are expected to be familiar with simulation technologies and have proficiency in Computer Aided Engineering (CAE) solutions, which would also give them an edge in the …
