**The Durometer to Young’s Modulus Calculator is an online conversion tool that allows you to convert durometer hardness values to their corresponding Young’s modulus values. **

This calculator is particularly useful in the field of **materials science** and **engineering**, where understanding the relationship between **hardness** and **elasticity** is crucial for selecting the appropriate materials for various applications.

## Durometer to Young’s Modulus Calculator

**Example 1: Converting Shore A Hardness to Young’s Modulus for an Elastomer**

Given:

**Shore A Hardness**= 70

To calculate **Young’s Modulus (MPa)**, we use the formula:

**Young’s Modulus (MPa)** = 0.0981 × (56 + 7.66 × **Shore A Hardness**) **Young’s Modulus (MPa)** = 0.0981 × (56 + 7.66 × 70) **Young’s Modulus (MPa)** = 0.0981 × (536.2) **Young’s Modulus (MPa)** = 52.6 MPa

Therefore, for an **elastomer** with a **Shore A hardness** of 70, the corresponding **Young’s Modulus** is approximately 52.6 MPa.

**Example 2: Converting Shore D Hardness to Young’s Modulus for a Plastic**

Given:

**Shore D Hardness**= 80

To calculate **Young’s Modulus (MPa)**, we use the formula:

**Young’s Modulus (MPa)** = (-0.0057 × **Shore D Hardness**^3) + (1.8 × **Shore D Hardness**^2) + (32.7 × **Shore D Hardness**) + 28.6 **Young’s Modulus (MPa)** = (-0.0057 × 80^3) + (1.8 × 80^2) + (32.7 × 80) + 28.6 **Young’s Modulus (MPa)** = (-0.0057 × 512000) + (1.8 × 6400) + (2616) + 28.6 **Young’s Modulus (MPa)** = (-2918.4) + 11520 + 2616 + 28.6 **Young’s Modulus (MPa)** = 11246.2 MPa

Therefore, for a **plastic** with a **Shore D hardness** of 80, the corresponding **Young’s Modulus** is approximately 11246.2 MPa.

**Example 3: Converting Shore A Hardness to Young’s Modulus for a Rubber Gasket**

Given:

**Shore A Hardness**= 45

To calculate **Young’s Modulus (MPa)**, we use the formula:

**Young’s Modulus (MPa)** = 0.0981 × (56 + 7.66 × **Shore A Hardness**) **Young’s Modulus (MPa)** = 0.0981 × (56 + 7.66 × 45) **Young’s Modulus (MPa)** = 0.0981 × (400.7) **Young’s Modulus (MPa)** = 39.3 MPa

Therefore, for a **rubber gasket** with a **Shore A hardness** of 45, the corresponding **Young’s Modulus** is approximately 39.3 MPa.

These examples demonstrate **how to calculate Durometer to Young’s Modulus**, that can be used to convert **durometer hardness** values to **Young’s modulus** values for different **materials**.

The calculations follow the formulas provided in the article, which are based on **empirical relationships** between **hardness** and **elasticity**.

## What is Durometer to Young’s Modulus?

**Durometer** is a measure of the **hardness** of a material, typically used for **rubbers**, **elastomers**, and other **non-rigid materials**. It is expressed on a **Shore scale**, which ranges from 0 (softest) to 100 (hardest).

The most commonly used Shore scales are **Shore A** and **Shore D**, with Shore A being suitable for softer materials and Shore D for harder materials.

**Young’s Modulus**, also known as the **Elastic Modulus**, is a measure of the **stiffness** or **elasticity** of a material.

It represents the relationship between **stress** (force per unit area) and **strain** (deformation) in the **linear elastic region** of a material’s stress-strain curve.

Young’s Modulus is typically expressed in units of **pressure**, such as **Pascals (Pa)** or **Pounds per Square Inch (PSI)**.

### Durometer to Young’s Modulus Calculation Formula

The formula used to convert **durometer hardness** to **Young’s modulus** depends on the **material type** and the **durometer scale**. Here are two common formulas:

**For elastomers and rubbers (Shore A):**Young’s Modulus (MPa) = 0.0981 × (56 + 7.66 × Shore A Hardness)**For plastics (Shore D):**Young’s Modulus (MPa) = (-0.0057 × Shore D Hardness^3) + (1.8 × Shore D Hardness^2) + (32.7 × Shore D Hardness) + 28.6

It’s important to note that these formulas provide **approximate values**, and the actual Young’s modulus of a material may vary due to various factors, such as **temperature**, **strain rate**, and **material composition**.

## What is the formula for Young’s modulus of hardness?

The formula used to convert **durometer hardness** to **Young’s modulus** depends on the **material type** and the **durometer scale** used (Shore A or Shore D). Here are the two common formulas:

**For elastomers and rubbers (Shore A):****Young’s Modulus (MPa)**= 0.0981 × (56 + 7.66 ×**Shore A Hardness**)**For plastics (Shore D):****Young’s Modulus (MPa)**= (-0.0057 ×**Shore D Hardness**^3) + (1.8 ×**Shore D Hardness**^2) + (32.7 ×**Shore D Hardness**) + 28.6

## What is the difference between durometer and modulus?

**Durometer** and **modulus** are two different properties used to characterize materials:

**Durometer**is a measure of the**hardness**of a material, specifically for**rubbers**,**elastomers**, and other**non-rigid materials**. It is expressed on a**Shore scale**, ranging from 0 (softest) to 100 (hardest), with Shore A and Shore D being the most common scales.**Modulus**, particularly**Young’s Modulus**, is a measure of the**stiffness**or**elasticity**of a material. It represents the relationship between**stress**(force per unit area) and**strain**(deformation) in the**linear elastic region**of a material’s stress-strain curve.**Young’s Modulus**is typically expressed in units of**pressure**, such as**Pascals (Pa)**or**Pounds per Square Inch (PSI)**.

In simple words we can say that, **durometer** measures **hardness**, while **modulus** (specifically Young’s Modulus) measures **elasticity** or **stiffness**.

## How do you calculate Young’s modulus of rubber?

To calculate the **Young’s modulus** of **rubber**, you need to know the **Shore A hardness** value of the rubber sample. Then, you can use the following formula:

**Young’s Modulus (MPa)** = 0.0981 × (56 + 7.66 × **Shore A Hardness**)

This formula is specifically designed for **elastomers** and **rubbers** using the **Shore A hardness** scale.

For example, if the **Shore A hardness** of a rubber sample is 70, you would calculate the **Young’s Modulus** as follows:

**Young’s Modulus (MPa)** = 0.0981 × (56 + 7.66 × 70) **Young’s Modulus (MPa)** = 0.0981 × (536.2) **Young’s Modulus (MPa)** = 52.6 MPa

Therefore, for a rubber sample with a **Shore A hardness** of 70, the corresponding **Young’s Modulus** is approximately 52.6 MPa.
