TABLE 61. THE LIMIT OF PLASTICITY OF ICE FOR FLEXURE IN 

 KG/CM2 AS A FUNCTION OF TEMPERATURE 



TABLE 62. THE LIMIT OF PLASTICITY FOR COMPRESSION OF 

 VARIOUS TYPES OF ICE 



TABLE 63. AVERAGE LIMITS OF PLASTICITY IN KG/CM^ 



Table 63 shows the limit of plasticity for fracturing, determined for the same layers for 

 which the limit of plasticity of compression was determined for one of the series of tests. 



Each value in this table is an average of at least 100 determinations. In the majority of 

 cases, the number of determinations was greater, and in some cases dealing with the limit of 

 plasticity during compression, the number of determinations used in determining values in the 

 table exceeded 300. Thus, the averages given in the lower part of the table are averages of many 

 hundreds of determinations . The air temperature during the test was from -2 ° to -22 °, however 

 no obvious interrelationship between the temperature and the limit of plasticity could be established.
