Mechanical Engineering Design – Basic learning and understanding

Share This: To design is either to formulate a plan for the satisfaction of a specified need or to solve a problem. If the plan results in the creation of something having a physical reality, then the product must be functional, safe reliable, competitive, usable, manufacturable, and marketable. To remind us that designs are constrained, and have to exhibit qualities ... Read More »

The Metallurgical Crystal Structure of Titanium

Share This: Like a number of other metals – e.g. Ca, Fe, Co, Zr, Sn, Ce, and Hf – titanium can crystallize in various crystal structures. However, each modification is only stable within particular temperature ranges. The complete transformation from one into another crystal structure is called allotropic transformation; the respective transformation temperature is called the transus temperature. Pure titanium, ... Read More »

Fundamentals of Heat Transfer (What is it?)

Share This: Heat transfer is the flow of thermal energy driven by thermal non – equilibrium (i.e. the effect of a non – uniform temperature field), commonly measured as a heat flux (vector), i.e. the heat flow per unit time (and usually unit normal area) at a control surface. The aim here is to understand heat transfer modelling, but the ... Read More »

Why Heat and Mass Transfer?

Share This: Heat transfer and mass transfer are kinetic processes that may occur and be studied separately or jointly. Studying them apart is simpler, but both processes are modelled by similar mathematical equations in the case of diffusion and convection (there is no mass – transfer similarity to heat radiation), and it is thus more efficient to consider them jointly. ...

Analysis of Chip Formation

Share This: The first step in a consideration of the mechanics of chip formation is to identify correctly the type of chip involved (steady state, BUE, discontinuous, wavy, or sawtooth). If, at the outset of a metal cutting analysis, an incorrect chip type is assumed, the results obtained may be misleading. It is extremely difficult to predict the type of ... Read More »
