1. COMPUTER AIDED ENGINEERING (CAE)

 

• One of the fundamental features of Engineering is to make trade-offs to get optimal designs

 

• If we overdesign, then all designs become simple, but more expensive, and more difficult to manufacture

 

• If we underdesign, then our design will not fulfill our requirements

 

• Therefore we use knowledge and tools to achieve designs which are ‘just right’.

 

• There are many physical factors which can affect the quality of a design,

 

- Yield stress failure

- Excessive deformation

- Insufficient heat transfer

- Kinematic interference

- Too much/little air drag

- Resonance at wrong frequency

- Electromagnetic interference effects

- Non uniform cooling effects (eg. warping in plastic parts)

- etc.
