Explain the Maxwell Model for a viscoelastic material and derive the relationship between stress (σ) and strain (ε) in terms of the spring's Young's modulus (E) and dashpot's coefficient of viscosity (η).

The Maxwell Model consists of a spring and a dashpot in series. The relationship between stress (σ) and strain (ε) is σ = Eε + η(dε/dt) Signup and view all the answers

Describe the Kelvin-Voight Model for a viscoelastic material and derive the relationship between stress (σ) and time (t) when the material undergoes a step strain change.

In the Kelvin-Voight Model, a spring and dashpot are connected in parallel. The relationship between stress and strain is σ = hε + Eε. The relationship between total stress (σ) and time (t) is σ = σ0 + (E/η)ε0(1-e^(-tη/E)). Signup and view all the answers

Explain the use and principle of an atomic force microscope (AFM) in biomedical engineering.

AFM is used to image surfaces at the nanoscale by scanning a sharp tip over the sample. It measures forces between the tip and the sample, providing high-resolution topographical and mechanical information. Signup and view all the answers
