Peel testing is a basic mechanical test used to measure the performance of adhesive bonds. Peeling test involves applying a tensile force to a flexible substrate joined by an adhesive, which can be bonded to another flexible substrate (such as tape, film, or rubber) or a rigid substrate (such as metal, rigid plastic, or composite). UnitedTest have a wide range of peel testing equipment that can be configured for your exact test application.
The tensile test, also known as tension test, is the most fundamental and widely used mechanical property test in the field of material science and engineering. It evaluates a material’s behavior under axial tensile loads, measuring core performance indicators such as tensile strength, yield strength, elongation at break, and elastic modulus. These parameters directly determine a material’s ability to withstand stretching forces in practical applications, serving as the cornerstone for material selection, product design, quality control, and R&D innovation across industries. UnitedTest, a professional provider of mechanical testing equipment, offers high-precision tensile testing systems with customizable configurations, ensuring accurate, repeatable, and reliable test results for diverse materials and scenarios.
The compression test is one of the most fundamental and widely used mechanical property tests, focusing on evaluating a material’s behavior under axial compressive loads. It measures key performance indicators such as compressive strength, yield strength, compressive modulus, and deformation capacity, which are critical for determining a material’s suitability for applications where it must withstand squeezing, pressing, or crushing forces. This test is applicable to almost all solid materials, from metals and plastics to composites and building materials, and serves as a cornerstone for material R&D, quality control, and structural design across industries. UnitedTest, a professional provider of mechanical testing equipment, offers high-precision compression testing systems tailored to diverse industrial needs, ensuring reliable and repeatable test results.
The flexural test, also known as the bending test, is a fundamental mechanical property test that evaluates a material's ability to withstand bending loads without fracture or permanent deformation. It focuses on measuring key performance indicators such as flexural strength, flexural modulus (stiffness), and flexural strain, which are critical for assessing how materials behave under non-tensile or compressive stress conditions in practical applications.
The tear test is a critical mechanical property evaluation method designed to assess a material’s ability to resist the propagation of a pre-existing crack or tear under applied force. Unlike tensile tests that focus on uniform stretching, tear tests simulate real-world scenarios where materials encounter localized damage (e.g., a nick in a film, a cut in fabric) and measure the force required to extend that damage. Key indicators derived from this test include tear strength, tear energy, and tear propagation resistance, which are essential for determining the durability and reliability of flexible and semi-rigid materials. UnitedTest, a professional provider of mechanical testing equipment, offers high-precision tear testing systems with customized fixtures, ensuring accurate and repeatable results for diverse industrial materials.
The shear test is a critical mechanical property evaluation method that assesses a material’s ability to resist tangential forces that cause adjacent internal material layers to slide past each other. Unlike tensile or compression tests that focus on axial loads, shear tests simulate real-world scenarios where materials endure parallel, opposing forces—such as bolted joints under load, adhesive bonds, or structural components subjected to lateral stress. Key indicators derived from this test include shear strength, shear modulus, and shear strain at failure, which are essential for ensuring the structural integrity and reliability of materials and components. UnitedTest, a professional provider of mechanical testing equipment, offers high-precision shear testing systems with customized fixture solutions, catering to diverse industrial material requirements and ensuring accurate, repeatable test results.
The puncture test is a critical mechanical property evaluation method designed to assess a material’s ability to resist localized penetration or rupture when subjected to a concentrated load from a sharp or blunt probe. Unlike tensile or flexural tests that focus on uniform stress, puncture tests simulate real-world scenarios where materials encounter sudden, point-like impacts or forced penetration. This test is widely used for flexible materials (e.g., films, fabrics) and rigid materials (e.g., plastics, metals, composites) alike, providing key data on puncture strength, puncture energy, and failure modes.
