Penilaian Menengah Rendah (commonly abbreviated as PMR; Malay for Lower Secondary Assessment) was a Malaysian public examination targeting Malaysian adolescents and young adults between the ages of 13 and 30 years taken by all Form Three high school and college students in both government and private schools throughout the country from independence in 1957 to 2013.
The strain hardening exponent (also called the strain hardening index), usually denoted , is a measured parameter that quantifies the ability of a material to become stronger due to strain hardening. Strain hardening (work hardening) is the process by which a material's load-bearing capacity increases during plastic (permanent) strain , or ...
The selection of the strain rate is very important because the susceptibility to cracking may not be evident from result of tests at too low or too high strain rate. For numerous material-environment systems, strain rates in range 10 −5 - 10 −6 s −1 are used; however, the observed absence of cracking at a given strain rate should not be ...

where σ is the applied stress, E is the Young's modulus of the material, and ε is the strain. The spring represents the elastic component of the model's response. [2] Dashpots represent the viscous component of a viscoelastic material. In these elements, the applied stress varies with the time rate of change of the strain:
