• The stress-strain curve of Fig. 3.1 is developed within the member with the difference that the diagram is rotated counterclockwise through 90° until its strain axis becomes vertical. • Further, the strain axis is replaced by the depth of section as it is directly proportional to the strain. • This resulting diagram is shown in Fig. 3.2,

It is well known that concrete behavior is highly affected by both pressure and strain rate. But, considering the complexity and short duration of these events, it is technically impossible to separate the contributions of each to the fracturing processes and strength increase [41].In reality, under dynamic loading conditions both pressure and rate increase simultaneously.
