MEYER LAW OF ESTERIFICATION (1894) When esters are formed from alcohols, the esterification reaction is speeded by the use of acids, but those acids are reduced in their effect on the reaction in the presence of some aromatic acids.

MEYER LAW OF INDENTATION (MATERIALS) (1908) This is an experimental, exponential relation that describes the indentation of a hard metal sphere on a plane metal surface (Fig. M.3) and has been found applicable to plastics, under static conditions. The empirical relation is: W = k dn where W = applied load k, n = constants depending on materials involved and sphere diameter (n = 2 for plastic, n = 3 for fully elastic) d = chordal diameter of remaining indentation

Meyer’s law is known to be a selected valuable model that enables us to scrutinize the general mechanical characterization (received as ISE: typical decrement in the Vickers microhardness parameters with the applied indentation test loads, and RISE: unusual increment in the Vickers microhardness parameters with the applied indentation test loads) of material under external stress. In terms of Meyer’s law (provided below in detail), the variation of microindentation test load (F) is quantitatively determined by a Meyer constant and exponential power of n for the indenter diagonal size [19]:
