DesignTech Systems Interview Questions, Process, and Tips for Experienced

CAE stands for Computer-Aided Engineering. It is the use of computer software to simulate performance and optimize designs before physical prototypes are built.

• CAE involves using computer software to analyze and simulate the performance of engineering designs.

• It helps in optimizing designs, reducing the need for physical prototypes and testing.

• Common applications of CAE include structural analysis, fluid dynamics simul...read more

FEA stands for Finite Element Analysis, a computerized method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects.

• FEA is a numerical technique used to analyze the behavior of structures or components under various conditions.

• It divides a complex structure into smaller, simpler parts called finite elements to simulate the behavior of the entire structure.

• FEA ...read more

RBE2 and RBE3 are different types of rigid elements used in finite element analysis.

• RBE2 connects multiple grid points to a single reference grid point with rigid bars or beams.

• RBE3 connects multiple grid points to a single reference grid point with independent springs or dampers.

• RBE2 is suitable for transferring loads in a single direction, while RBE3 allows for more flexibility in load transfer.

• RBE3 is more computati...read more

Ductile materials can undergo significant plastic deformation before failure, while brittle materials fail without significant deformation.

• Ductile materials can be stretched into wires or hammered into thin sheets without breaking.

• Brittle materials break with little or no plastic deformation.

• Ductile materials have high toughness and are able to absorb a large amount of energy before fracturing.

• Examples of ductile mater...read more
