Form Finding Experiments Trabecular Bone
- Growth follows the course of stress lines along the bone and maximum trabeculae develop along the lines of maximum stess. - Both tensile and compressive forces are present and correspond to the lines of forces. - Adaptation to alternative external loads. - Spongy-like structure
