Composite Pipe Repair Using Abaqus FEA

A damaged composite pipe was modelled in Abaqus to compare the structural recovery achieved by external patch repair and internal reinforcement. Stress, displacement and impact loading response were used to judge repair effectiveness.

Step 01

Pipe Geometry and Damage Setup

The study starts by creating the composite pipe geometry and defining the local damage region. The cracked baseline model is used to show how the defect concentrates stress and reduces load-carrying capacity.

Step 02

Boundary Conditions, Pressure and Mesh

Internal pressure, end restraints and local mesh refinement were defined around the crack. The refined mesh helps capture the high stress and deformation gradients near the damaged zone.

Step 03

Cracked Pipe Baseline Results

The cracked pipe produced the highest stress and displacement values, with a reported peak stress of about 1.24 × 10² and displacement around 5.37 × 10⁻². This establishes the unrepaired damage case for comparison.

Step 04

External Patch Repair

An external composite patch was bonded around the damaged region to distribute the load away from the crack. The repair reduced the peak stress to about 6.96 × 10¹ and lowered displacement to about 2.36 × 10⁻².

Step 05

Internal Reinforcement Repair

The internal reinforcement case provided the strongest recovery for crack damage, reducing stress to about 4.82 × 10¹ and displacement to about 1.68 × 10⁻². This made it the preferred solution for axial crack repair.

Step 06

Impact Loading Comparison

Under impact-type loading, the external patch was more suitable because it spread the contact effect over a wider surface region. The final conclusion separates the best repair choice by damage mechanism: internal reinforcement for cracks and patching for impact response.

Orthotic Insole Pressure FEA

A shoe orthotic insole was modelled to analyse plantar pressure, stress and displacement. The study compares material behaviour and links the simulation workflow to practical insole design and manufacturing needs.

Step 01

Insole Geometry and Mesh

The orthotic insole was represented as a finite-element model with a dense mesh across the curved foot-support surface. This setup makes it possible to analyse localized deformation under plantar pressure.

Step 02

Pressure and Support Definition

A distributed pressure load was applied to the upper surface while the support condition restrained the underside. The model represents contact loading from the foot during use.

Step 03

Stress Response

The material study evaluates the Von Mises stress distribution across the insole. The stress plots identify where loads concentrate and whether the selected material can safely distribute pressure.

Step 04

Displacement and Material Comparison

The displacement plots compare how different insole materials deform under the same loading. Softer materials improve comfort but may deform more, while stiffer materials help retain shape.
