Youngs 模量弹簧应变

问：

我需要模拟钢应变。但是我不能增加足够的压力。如果我愿意，它的爆炸和阻尼值无法修复。

这是我的代码：

Vector3 delta = distance_joint.FirstNode.transform.position - distance_joint.SecondNode.transform.position;
float deltalength = delta.magnitude;

// Calculate strain
float strain = (deltalength - distance_joint.Distance) / distance_joint.Distance;

// Calculate the spring force based on Young's Modulus
Vector3 force = delta.normalized * SpringK * strain;

// Calculate relative velocity
Vector3 relativeVelocity = distance_joint.SecondNode.GetVelocity() - distance_joint.FirstNode.GetVelocity();

// Damping coefficient (you can adjust this value)
float dampingCoefficient = SpringDamping;

// Calculate the damping force based on relative velocity
Vector3 dampingForce = -dampingCoefficient * relativeVelocity;

// Combine spring force and damping force
force += dampingForce;

// Apply forces to the connected nodes
distance_joint.SecondNode.AddForce(force);
distance_joint.FirstNode.AddForce(-force);

骨架结构器

我想做一个汽车骨架。我需要模拟像钢一样的材料应变。
