metadata.name: dc.description.abstract
metadata.value: When we want to compare the strength of two materials, we compare the table values of quasi-static strength. However results of some experiments show that the strength ratio of the materials can change 
  with increase in rate of loading. Such "substitution effect" of material strength at different strain rates is studied in  this  paper.  It  is  shown  that  one  material  can  have  a  lower  dynamic  strength  for  a  higher  static  strength compared  to  the  other  material.  Tests  of  two  different  materials,  tests  of  mortar  and  concrete,  and  tests  of concrete with different water content are considered. It is shown that load-carrying capacity of materials and the substitution effect of material strength in a wide range of loading rates can be predicted by the incubation time criterion.
