Applied Force → Bone Stretch
Reset

Strain: 0.00, Stress: 0 MPa, Force: 0 N

Instructions and Explanations

• Slider ("Applied Force → Bone Stretch"): Use this slider to gradually increase the force applied to the bone. The green dot on the stress-strain graph represents the current state of the bone under this applied force.
• Elastic Region: When the bone is in the light green region on the graph (strain below the yield point), it stretches proportionally to the applied force. If the force is removed in this region, the bone returns to its original length.
• Plastic Region: Once the yield point is exceeded, the bone enters the orange region. Microcracks begin to accumulate in the bone, and permanent deformation occurs. If the force is removed here, the bone does not return fully to its original length.
• Microcracks: The small white lines represent microcracks forming progressively in the region that will eventually fracture. They accumulate cumulatively as the force increases, illustrating the internal damage within the bone.
• Fracture: As the applied strain approaches the fracture strain, the bone eventually breaks, shown by the white fracture line across the bone. Stress and strain values are frozen at this point to reflect material failure. (The slider is disabled once fracture occurs as the bone is nolonger a complete structure.)
• Reset Button: Press the Reset button to return the bone, graph, microcracks, and slider to the starting state.
• Graph Interpretation: The x-axis represents strain (deformation relative to original length), and the y-axis represents stress (force per unit area in MPa). Elastic, plastic, and fracture regions are highlighted with shaded colors and vertical lines to clearly indicate the key points.
