Structural Analysis

Numesys Structural Analysis Team provides computer-aided engineering services to its customers from various industries in order to validate whether the mechanical designs and end products have the required mechanical properties such as strength and fatigue life. Static and dynamic stress analysis, vibration calculations, thermal analysis are performed under environmental, operational and limit loads. Recommendations on design improvements are reported by our expert engineers. As such, Numesys Structural Analysis Team guides its customers in finding a durable, lightweight, economical, and easily manufactured design solution that fits the product requirements.


Structural behavior of a mechanical design is analyzed with the help of finite element analysis under environmental (gravity, wind, earthquake, transportation, etc.) and operational loads.The finite element analyses show results such as deformation, displacement, strain, and stress of the structure, and the integrity and functionality of the structure are interpreted by our experts. In this way, the product is validated to meet the necessary integrity under defined mechanical loads. Optimization studies are carried out with design improvement suggestions when necessary.
Engineering services are provided to validate the designs for the cases where the effect of mechanical vibrations are dominant in the design. Investigation of the vibration behavior of products operating under dynamic loads is vital for many applications, across various industries, such as aerospace and defence, turbomachinery, general machinery, household appliancesand automotive. With the help of finite element analysis performed by our engineers, critical natural frequencies and related mode shapes of the structures can be determined and possible resonance situations can be prevented. The effects of harmonic and random loads acting on the structure can also be calculated, to evaluate the strength and fatigue life.


Using the most advanced simulation and optimization tools and algorithms, our engineers provide services on objective based parametric optimization, determination of dependenciesand sensitivities between design parameters, creation of 1-D models or response surfaces and six sigma analyses. In this way, we help our customers determine the most suitable, lightweight, economical and robust design within the design constraints. As additive manufacturing methods have spread and started to be used in mass production, topology (shape) optimization methods have become a widely used method amongst mechanical designers. We provide structural analysis and topology (shape) optimization services in order to obtain the optimum CAD geometry that meets the mechanical requirements and compatible with new production methods.
Engineering services are provided in order to obtain the kinematics of mechanisms in working conditions such as determining the rigid-body components of motion (displacements, velocities, etc.), strength behavior of the parts (strain, displacement, etc.) and forces acting on the joints. In this way, important concepts, such as power requirements of the mechanism, joint/component strength, are determined, and design changes are recommended when necessary.


Determination of fatigue life of structures exposed to cyclic loads is one of the most important design criterion especially in industries where safety is indispensable, such as aviation, defense, and automotive. Thanks to advances in numerical technologies, finite element simulations stand out today as a practical and comprehensive tool for fatigue life determination. By using advanced methods and tools, our engineers assist our customers to determine the critical regions for crack initiation especially for metallic structures, determine the design life of critical components and identify the regions with critical stress hotspots and the necessary design changes required to meet the desired mechanical life of the product.


The material flow that will take place between the dies during forging can be predicted with a high level of precision, thanks to the processing of material properties depending on temperature, forming speed and forming quantity by specialized metal forming software with 3-dimensional, complex, non-linear solver. With the data obtained from these analyses, our customers are provided with vital information such as fold formation, press load, die filling status, and die stretching. In this way, our customers can reduce the error costs, which are quite high in metal forming processes.
In addition to static or quasi-static loads, products can also be exposed to instant but extreme loads within their life cycle. Some examples are accidental drop during transportation, being exposed to impact or shock loads, different crash scenarios critical for the automotive industry, and evaluation of a ballistic projectile or the target for the defense industry. Through advanced explicit structural analysis tools, we help our customers validate their design and material selection for the desired structural performance.
The pressure load that structural or non-structural components will be exposed to under blast loads is calculated, and time transient structural analyses are performed using explicit numerical codes. As a result of these analyses, many evaluations are performed such as determination of damage due to blast wave, safe stand-off distance to the threat, secondary effects due to particle fragmentation. Specifically we help our clients in the defense industry to provide the desired level of safety to comply with the industry standards and guidelines for underwater mine blast and landmine blastfor naval and land platforms, respectively.
We help our clients with their designs of indoor environments such as buildings, rooms, car parks, tunnels, and mines through CFD simulations. Many issues such as temperature and velocity distribution inside a room, the affected region of the air blown or sucked due to the fans, the emission and discharge of gases in the event of a fire or smoke propagation, the location and direction of the fan selection, the location of the blowing and suction grilles can be examined under this topic with CFD analyses.
